1. From the chemicals listed on your lab handout, write down the weak acid (with its pKa) and its conjugate base that would create a buffer that best fits your protein. Would you expect for your buffer to have more acid or more base? My assigned protein is Xylanase and has an optimum pH of 5.5.
2. Buffers are used to the inhibit the change of pH upon the addition of strong acids and bases. If you were to add 0.1 M HCl to your buffer, would you expect the pH to change? If so, would the pH increase or decrease? What would happen if 0.1M NaOH were to be added instead?

3. Keeping your buffer composition from question 1 in mind, would you expect to use a larger volume of HCl or NaOH to change the pH of the buffer solution by one unit? Explain.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

lol for the pointsss

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
