Response Surface Optimization Of Treated Turbid Water Using Banana Stem Juice Essay

In this analysis of the factors that affect reaction rates, the purpose of the lab was to find the relationship between the change of surface area and reaction rate using Alka Seltzer tablets. In order to determine the connection between the surface area and reaction rate, the time it took for the reaction to finish was recorded for five different surface areas of the tablet. The ceasing of the production of bubbles and fizz and the complete dissolution of the tablet was established as the finished reaction. Water and the Alka Seltzer reacted to form Carbon Dioxide bubbles. As displayed in Graph 1, the relationship between surface area and reaction rate was represented by the positive slope and trend line. Through the data and results, it was concluded that as surface area increases, the rate of reaction also increases representing a direct relationship. The increase in the surface area created more contact and collisions, which increased the rate of the

In Part C of the experiment, the process completed in Part B was performed again on the six Kool-Aid drink samples: black cherry, cherry limeade, grape, mixed berry, strawberry, and tropical punch. The cherry limeade, grape, mixed berry, and tropical punch samples were undiluted stock solutions that were used in the SpectroVis. The black cherry solution was diluted with a 2-fold dilution. The 3 mL of black cherry solution was diluted with 3 mL of deionized water. This was done because the Red 40 dye was too concentrated. The strawberry solution was first diluted by a 2-fold but the absorbances values were too high and fell outside the acceptable range of 0-1. Therefore, 8 mL of strawberry solution was diluted with 12 mL of deionized water. These values for all of the solutions were recorded in Table 5. The solutions were emptied down the sink. All the glassware and cuvettes were rinsed with deionized water and dried. The volumetric flasks and caps were returned to the appropriate containers.

Solutions of 6M H2SO4, 6M NH3, 6M HCl, 6M NaOH, and 1.0 M of NaCl, 1M Fe(NO3)3, 1M NiSO4, 1M AgNO3, 1M KSCN, 1M Ba(NO3)2, and 1M Cu(NO3)2 were given in separate test tubes. The color of possible precipitates, ions, acid-base behaviour, odor and solubility rules were conducted and were reported in Table 1. The key information about a mixture of two solutions was

Within the context of the scenario, we find that a distilling company that markets a popular banana liqueur is having problems. The banana plantation that they use to create their banana extract was hit hard by a hurricane and their reserves of extract are running low. It is our job to formulate a synthetic banana flavoring and determine whether it will work as a substitute for natural extract. The problem that the distilling company foresees is that the process used to create

Acidic Relations in Chemistry is the topic of this experiment. In this experiment, the scientists will be testing the strength of pH and the amount of TDS (total dissolved liquids) in both gunpowder green tea and caffeinated black coffee. The independent variables are the caffeinated beverages and the dependent variables are the pH and TDS levels of the gunpowder green tea and black coffee. The constants are the way we measure the pH and TDS of the caffeinated beverages

When recording my results I realized that my hypothesis was not acceptable the cheese cloth working as a filtration system removed most of the contaminants from the water with the vinegar added leaving very little change. In the other beakers it was as I expected, there was

This report discusses Team 2’s design for a water filtration device and turbidity sensor, to provide safe, clean drinking water to the rural community of Espiritu Santo, Vanuatu. The community is heavily dependent on the weather to collect rain water however, between May and October, the dry period restricts their water supply, leading to sickness and death through the drinking of unclean water.

Water availability of both surface and ground water has become a major problem due to high demand. On average, 320 gallons of water are used per day by each household in America, 30 percent of which is used outdoors (EPA, 2015). In Florida alone, total water withdrawals are expected to increase by almost 21 percent by the year 2030 (Water use trends in Florida, 2014). I believe the high volume of water being used is not the sole issue; it is the source of our water as well as our water management practices. Some experts estimate that as much as 50 percent of water used for outdoor irrigation is lost through evaporation (EPA, 2015). This loss of water happens when plants or grasses are watered at certain times during the day and is a direct result of Florida’s water mismanagement. Commercial and residential vegetation has been watered too often and at the wrong times for far too long and it needs to stop unless we want to see our aquifers dry up entirely.

The mass of the small beaker/flask and solution for each trial was found and recorded by using 50 mL graduated cylinders to add increasing 5 mL increments of vinegar, from 0 to 35 mL, and decreasing 5 mL increments of water, from 35 to 0 mL to the eight small beakers or flasks and weighed on an analytical balance. Accordingly, the mass of each of the eight Alka-Seltzer Tablets was determined and recorded. Moreover, the tablets were each dropped in their respective beakers/flasks, and allowed to fizz, without spilling over. The loss of mass of CO2 was furthermore ascertained by finding change in mass of each of the solutions after the fizzing stopped from the value of the mass of the Alka-Seltzer tablet plus the mass of the solution and beaker/flask. Further, using the loss of mass of CO2 for each trial and the balanced equation, the amount of NaHCO3 reacted and percent by mass in the tablet were identified. After determining the class average and the standard deviation for each trial, and plugging it into a scatter plot, the change of slope showed the true percent by mass of NaHCO3 in Alka-Seltzer tablets.

In the second experiment, I filtered water in a similar matter as to how water is properly filtered in order to purify it to drink it. The materials used in this experiment were 100 mL potting soil, beakers, 40 mL sand, 20 mL activated charcoal, 60 mL Gravel, alum, bleach, cheesecloth,

Hurricane Katrina destroyed the wonderful city of New Orleans leaving its citizens to rot. In Trouble the Water we got an inside look at what the city went through post Hurricane Katrina and the government’s response to save the people in danger. The film displays one family’s quest to survive the devastating effects of Hurricane Katrina.

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially permeable membrane from a high water concentration to a low water concentration.

The retained solution from the NaHCO3 extraction was used to precipitate the P-toulic acid. Drop wise 3M HCl was added to the extracted solution carefully until no more precipitate was formed and the solution tested acidic, with a pH reading less than 3 as indicated by pH paper testing. A piece of clean filter paper was then weighed and the mass recorded in a lab notebook. A vacuum filtration system was constructed with a Buchner funnel

Clean water supply is essential in establishing and maintaining a healthy community. There are two sources of water supply which are the surface water and ground water. Most natural waters are not suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals. In addition, as a city grew, wastes from human activities contaminate most of the water supplies. Water treatment plays an important role to properly treat a contaminated source of water supply in order to protect the health of consumers. Water treatment process is defined as a process of eliminating pollutants from untreated water to produce a biologically and chemically risk-free water, which is both potable and palatable for human consumption

The disposal of untreated wastewater coming from the industries into the water bodies will pollute the water bodies because of its high concentrations. So, the wastewater produced from the industry should be treated properly to meet the permissible limits given by central and state pollution control boards. Therefore it is necessary to treat the wastewater properly with the help of an appropriate treatment plant. However, the treatment plant even though properly planned may not work satisfactory because of several reasons. Hence, it is essential to evaluate the treatment plant considering individual treatment unit in the entire treatment flow. In the present work emphasis has been given to the study of the performance of treatment facilities because of its importance in the conventional treatment of wastewater. Hence, the literature review related to the evaluation of the entire treatment process along with biological treatment process particularly suspended growth process Activated Sludge Process (ASP), attached growth process Trickling Filter (TF) and a combination of the both suspended and attached growth process Hybrid Reactor (HR) is presented in the following sections of this chapter.
