ABSTRACT The purpose of this experiment was to see how the amount of baking soda dissolved in vinegar would affect the pH of the vinegar. We conducted the experiment by testing different amounts of baking soda in constant amounts of vinegar, and dropping the solutions on pH paper. By comparing the colors on the pH paper to a list of colors in relation to numbers on the pH scale, we were able to find out that as more baking soda is added, the pH of the solution goes up as well. INTRODUCTION Ocean
The mid to late twentieth century and the twenty first century have been devastating to the world’s oceans in terms of pollution, overfishing, ice caps melting, destruction of habitat, and increasing amounts carbon dioxide being dissolved into the water. These are only a few of the seemingly endless problems humans have introduced to the oceans. Things like the ice caps melting affect how basic aspects of the oceans function. Pollution and destruction of habitat affect nearly every species of marine
Girard Immanuel Soriano Ecological Principles Lab 9/25/15 Lab Group: I The Effect of C02 Concentration on the Photosynthetic Rate of Algae Introduction: How does the C02 concentration of algal solution affect the photosynthetic rate of Algae? In this experiment, algae solutions of different concentrations of carbon dioxide, on algal growth are tested to determine the effect of varying concentrations of carbon dioxide, on algal growth over a period of nine days. The rate of photosynthesis was
Copepods are good bio indicators of the aquatic ecosystem as their presence can depict the quality of water in aquatic ecosystem. The death of Copepods in week 3 can be due to various factors such as enormous increase in the salinity of the water from 223 to 257 and the temperature wasn’t high enough (optimum temperature 28degree Celsius).(Rhyne et al 2009; Nielsen et al 2003) Copepod existence did not increase when there was rise in salinity and temperature as they were not able to tolerate warm
Ocean’s Declining pH is Destroying Our Environment Sometimes called “climate change’s equivalently destructive twin”, ocean acidification is becoming more and more noticeable as the seawater’s changing chemistry begins to cause environmental and economical problems. When the Industrial Revolution began around 1760, fossil fuel–powered machines gained an immense amount of accessibility and popularity. Since then, carbon dioxide (CO2) levels in the atmosphere have risen enough to change the pH of the world’s
The ocean is the largest part of the carbon cycle, where more than 25% of the carbon dioxide (CO2) emitted each year into the atmosphere is absorbed. CO2 is a greenhouse gas and due to it’s relatively high concentations in the atmosphere it is the biggest contributor to the enhanced greenhouse effect and is responsible for climate change (Biello, 2009). Naturally occurring ocean acidification is being accelerated by an excess of CO2 being absorbed into the oceans, which is due to the increasing
Human Impacts on the Environment: Ocean Acidification Ecological human effects on the planet are now about 40% greater than the planet can support in a sustainable fashion (Grossman, 2010). One of the many areas with significant damage is the marine biosphere. Ocean acidification is a great threat to marine and subsequently human life. The pH level in the ocean has been a relatively constant 8.15 to 8.25 and organisms have evolved under these circumstances for over 50 million years. However
from this experiment relates to the climate change and the ocean temperature. Ocean holds great capacity of carbon dioxide. When the temperature in the environment boosts due to global warming, the ability for the ocean to hold carbon dioxide directly determines the amount of carbon dioxide released into the atmosphere. Since carbon dioxide itself allows to absorb great quantity of infrared radiation, so glaciers, ice caps and snow on the top of the mountain will melt due to greenhouse effect. Progressively
Alka Seltzer Dissolving at Different Temperatures The variable that I will change will be the temperature of the water that the Alka Seltzer is put in. For my results I will measure the time taken for the Alka seltzer tablet to completely dissolve in water at different temperatures. Input variables: * Varying surface area of Alka-Seltzer tablet, i.e. if cut into smaller pieces or crushed it will increase the surface area. (If the surface area is increased (more powdered) the rate
revolves around the pH level of the water in the oceans. According to Ocean Acidification by Gattuso and Lina “Ocean Acidification is a reduction in the pH of the ocean over an extended period, typically decades or longer, caused primarily by the uptake of CO 2 from the atmosphere” Scientists use the pH scale to describe the strength of acids and bases. The pH scale ranges from 0 to 14 with 0 being the most acidic and 14 the most basic. Gattuso and Lina address that, “Once dissolved in seawater, CO 2
