  • Using The Henderson-Hasselbalch Solutions Of Specific Ph

    1257 Words  | 6 Pages

    its conjugate base required to prepare the buffer solutions of specific pH. Examine pH behavior of buffer solutions using previously studied methods of measuring pH. Reinforce the proper use of volumetric glassware in preparation of solutions of a required concentration. Practice with titration technique in the determination of a buffer capacity. Introduction: A buffer solution is one that is resistant to change in pH value when small amounts of a strong acid or base are added. For example

  • Environmental Ph Influences And Determine The Shape Of Enzymes

    1745 Words  | 7 Pages

    Abstract Environmental pH influences and determine the shape of enzymes. Because of their optimum pH, enzymes have points of high and low activity. pH activity was measured to observe how amylase and catechol oxidase work together to breakdown starch in salivary glands. It was hypothesized that there would not be amylase activity when exposed to an acidic or basic pH environment. Therefore, amylase has an optimal pH level where activity is most active. It was suggested that the rate of reaction

  • Investigating the Effect of Ph on the Activity of the Enzyme Catalase.

    4164 Words  | 17 Pages

    Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide, a powerful and potentially

  • The Effects of Ph and Concentration Levels on Catecholase Essay

    1272 Words  | 6 Pages

    activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic, the catecholase was less

  • The Effect Of Concentration On The Ph Levels Of A Base Level

    894 Words  | 4 Pages

    configuration of an enzyme would stir the catalytic activities, factors including pH and temperature influence this and result in browning, a chemical change. Enzyme are known to act rapidly, therefore if it placed in a high temperature this would begin the breaking down and denature process which present less reaction. On the other hand if temperature is drop to freezing levels the enzyme would slow down or cease. A change in pH levels cause the enzyme to adapt to the various ranges however it will denature

  • The Effect of pH on the Activity of the Enzyme Amylase Essay

    1084 Words  | 5 Pages

    The Effect of pH on the Activity of the Enzyme Amylase Aim :- To find the effect of pH on the activity of the enzyme amylase. An enzyme is a type of protein found in all living cells. Enzymes act as biological catalysts, breaking down substrates without needing a high temperature, allowing all the chemical reactions of metabolism to take place, regulating the speed at which they progress, lowering the activation energy and providing a means of controlling individual

  • Investigating The Relationship Between Ph And Water Hardness

    2502 Words  | 11 Pages

    The purpose of this investigation was to determine the relationship between pH and water hardness. Water samples from above the Mount Morgan mine site and below the Mount Morgan mine site were also compared. 8.1 Analysis of the Data It was hypothesised that the water sample from above the mine site would be of better water quality than the sample from below the mine site. It was found that this was, in fact, the case. As seen in Table 7.2, the above sample had lower acidity, hardness and conductivity

  • The Effect Of Temperature And Ph Levels On Enzyme Activity

    926 Words  | 4 Pages

    Joshua Kwon Sep 19, 15 Biology p 4 How Do Changes in Temperature and pH Levels Affect Enzyme Activity? Lab Report In biology class, we’ve learned that sugars produce energy and to use sugars to gain energy, an organism needs a proper enzyme should exist to break it down the chemical bonds of the sugar. Enzymes and proteins are important in organisms because they are involved in most chemical reactions that take place inside of an organism. Our example of an important enzyme was catalase

  • Essay on Lab1: Effect of Ph on Food Preservatives

    1343 Words  | 6 Pages

    Lab 1: Effect of pH on sodium benzoate, a food preservative Sheikh M Zakaria Person no. 36295651 TA: Synthia Gratia Date of Submission: 05/29/13 Abstract Sodium Benzoate is a common food preservative used in food products such as jams and jellies, soft drinks, pickles, condiments etc and in tinned products in the market. This experiment aimed to determine whether benzoic acid is formed from it’s superior soluble form sodium benzoate in stomach acid, which is simulated by HCl (pH=2). It has been

  • How Does Diet Affect the pH of a Body?

    588 Words  | 2 Pages

    How Does Diet Affect the pH of a Body? This experiment will investigate if small changes in my diet will alter the pH of my saliva compared to the 10 other subjects I will test it on. The objective of this experiment tests how the little changes in my diet and others affects the pH of saliva. Well, since my question is how my diet affects pH, I already know a few things. There are two possible types of food that affect the pH of a body, alkalizing and acidic foods. Alkalizing foods include: apples
