  • Investigating The Effect Of Protein Adsorption And Thrombus Formation On A Ph Essay

    1084 Words  | 5 Pages

    Introduction: PH sensors are used in many scientific laboratories to measure the hydrogen-ion concentration of a liquid substance and to determine the basicity and acidity of a liquid. PH meters measure the electrical potential difference between a reference electrode probe and a pH electrode probe. Since these probes are very sensitive, they are required to be kept cleansed from contaminants. If exposed to contamination, one risks faulty or unreliable data, since their accuracy is dependent on a

  • Lab Report On The Ph Of The Potential Hydrogen Ion Concentration Of A Solution

    1492 Words  | 6 Pages

    Lab Report Background Research pH is a measure of the potential hydrogen ion concentration of a solution. Solutions that have low pH’s or a ph level below 7 are considered acidic. Solutions that have a high pH level or above 7 are considered basic. The pH scale measures how acidic or basic a solution may be. Some examples of solutions that have high acidity and a low pH level are Battery acid, lemon juice, and vinegar. Some solutions that are basic and a high pH level are soapy water, baking soda

  • The Effect Of Ph, Temperature, And The Inhibitor Hydroxylamine On Brassica Rapa Peroxidase

    1513 Words  | 7 Pages

    The Effects of pH, Temperature, and the inhibitor Hydroxylamine on Brassica rapa Peroxidase Enzyme Sriya Bhamidipati Abstract. Peroxidase is an enzyme whose main function is to break down hydrogen peroxide. It is rich in content in the organism Brassica rapa, or the turnip. The purpose of this study was to investigate and observe the effects of pH, temperature conditions and the inhibitor Hydroxylamine on Peroxidase ‘s ability to break down Hydrogen Peroxide. By observing the absorbance change

  • How Different Ph Levels Affect The Population Growth Of Yeast

    1180 Words  | 5 Pages

    different pH levels affect the population growth of yeast, which was based on the mm of carbon dioxide produced. Through this, our independent variable was the pH level of solution added to the test tube of yeast and sugar. Our dependent variable was the mm of CO2 produced, indicating population growth. For this lab, the proper control was a test tube with the yeast and sugar but no pH solution added. This was useful to compare our data to because it wasn’t being changed by the pH. Therefore

  • The Effect Of Enzymes On Bacterial Cells, Namely Environments With Varying Phs ( Thomasch )

    735 Words  | 3 Pages

    Introduction/Hypothesis: This experiment was conducted to observe the effects of certain factors on enzymatic activity in yeast cells, namely environments with varying pHs (Thomasch). Enzymes play a large role in many different biochemical processes that occur throughout many different organisms. As a distinct subcategory of proteins, they are composed in the same manner as any other protein, with amino/carboxyl groups, and variable side chains that ultimately determine their structure,

  • How Does Soil Affect The Ph Of Water?

    1748 Words  | 7 Pages

    How does soil affect the pH of water? Abstract: During this lab, the pH of water in soil from a man made garden, a deciduous forest, and a river bank were tested after leaving it in containers for one, two, and three hours, coming out to a total of three trials with three different soils all together. After testing the pH of the water when being added to the soil for the desired amount of time and comparing it to the original water with no soil added, is then when each pH difference was observed and

  • The Effect Of Temperature On Daphnia By Changing Ph Levels And Measuring The Hear Rate

    1419 Words  | 6 Pages

    This experiment is being done to show the effect oh pH levels on daphnia by changing pH levels and measuring the hear rate. Introduction Daphnia magna are commonly used to test water toxicity, they are a vital part of fresh water ecosystems. They serve as a crucial role in food webs as they are a food source for smaller fish and invertebrates, and they also are a consumer of algae and bacteria (Elbert, 2005). They range from 2-5mm long these small crustaceans are also referred to as water fleas

  • The Depth Of The River Affect Its Overall Ph From Mid July 2015-

    801 Words  | 4 Pages

    Question: Does the depth of the river affect its overall pH from mid december 2015- to early january 2016? Knowledge Probe: According to.epa.gov/acidrain/measure/pH.html, pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. A pH of 7 is the most neutral you can get and 0 being the most acidic and 14 being the most basic. each level is 10 times more basic/

  • Investigating how pH effects the enzyme trypsin acting on coloured gelatin

    1436 Words  | 6 Pages

    determining the effects of pH on enzyme activity show that as the independent variable, pH, increases the dependent variable, percentage transmission, decreases. This is shown in the results as at the lowest pH, pH 4.0 the average percentage transmission is at its highest at 97%. At the highest pH, pH 8.0 the average transmission is 78.5%. This is also supported from the graph as it produces a negative gradient showing that as the percentage transmission will decrease with an increasing pH. This happens because

  • Investigating The Effect Of Ph On The Reaction Of A Poultry ( Enzyme ) Reaction Essay

    925 Words  | 4 Pages

    these enzymes will differ and be dependent upon several factors, such as consistency, size and shape of the molecule. Specific factor will be the concentration enzyme and substrate. I will conduct a controlled experiment to determine the influence of pH on the enzyme catalase and the release of oxygen. Hypothesis Acidic fluid on an enzymatic would react in different ways based on the strength of the acid solution. The stronger the acid solution, there will be more of a reaction and the stronger the
