Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution. Methods Verification of the Henderson-Hasselbalch equation

Economies of scale are the factors that lead to a reduction in average costs as a business increases in size. There are five economies of scale Purchasing Economies When businesses buy large numbers of components‚ for example materials or spare parts‚ they are able to gain discounts for buying in bulk. This reduces the unit cost of each item bought and gives the firm an advantage over smaller businesses which buy in small quantities. Marketing Economies

from entering your lungs. That is why in the Philippines‚ Local Government Units and Non-local Government Organizations together act to resolve air pollution. We all know about the smoking ban and the anti-smoke belching. But how about the large scale air pollution contributors? These are industries with operations that involve process that emits hazardous gases such as but not limited to NOx‚ SOx‚ COx‚ and CFCs in high quantity. The Department of Natural Resources mandated an air pollution policy

Chem 253—TA: Josh Lovell Lab 1: Effect of pH on a Food Preservative 6/11/13 Purpose: (1 point) To determine whether a chemical change occurs when Sodium Benzoate is acidified to Benzoic Acid. Theory: (2 points) Sodium Benzoate is a common food preservative found in jellies‚ jams‚ sodas‚ fruit juices‚ etc... Its acid‚ Benzoic Acid‚ is an organic preservative that stops the growth of bacteria‚ yeasts‚ and molds. Reaction: (3 points) Reaction: sodium benzoate + hydrochloric acid ( benzoic

Write an explanation of how any two factors affect the rate of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature

How does pH affect the activity of the Amylase? Abstract: In my experiment I aimed to observe how ranging pH levels will affect the rate in which amylase will break down the starch molecules. I will be measuring the time it takes for the dark liquid to disappear and leave a yellow brown liquid to be shown‚ which would show that there is no starch present in the solution because it would have broken into maltose by adding amylase. Results did not fully demonstrate what we expected in our hypothesis

CHEMICAL WEATHERING Chemical weathering is a process of alteration of rocks of the Earth’s crust. is a chemical decomposition process. is brought out by atmospheric gases and moisture. End product has a different chemical composition and poorer physical constitution. The process: Chemical change in the nature of rock takes place in the presence of moisture containing many active gases such as CO2‚ N2‚ H2‚ and O2. Rocks are made up of minerals. All the minerals in a rock are not in
