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

been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although

Experiment 3 : Preparation of Solutions and Buffers Objectives : 1. To study and understand the principle theory and formula of preparation of buffer and solution. 2. To learn the methods of buffer and solution preparation. 3. To focus on concentration units of molarity‚ percentage of concentration‚ and dilution of solution. Introduction : When a substance‚ called a solute‚ is dissolved in another substance‚ called the solvent‚ a solution is formed. A solution is known as a homogeneous

Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you put sugar

Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves

identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three

CAT 2007 Solutions Section I 1. Note that the price of Darjeeling tea remains constant after the 100th day (n=100). If the prices of the two varieties of tea become equal before n = 100‚ then 100 + 0.1n = 89 + 0.15n ∴ n = 220‚ which is not possible. (Since n has been assumed to be less than 100) ∴ The prices of the two varieties will be equal after n = 100‚ i.e.‚ when the price of Darjeeling tea = 100 + 0.1 × 100 = 110 ∴ 89 + 0.15n = 110 ∴ n = 140 2007 is not a leap year.
