If you added too much acetic acid to the milk solution , what would happen to...
explain why casein precipitates (curdles) when acetic acid is added to your milk mixture. What is the function of acetic acid. 5. This precipitation can also be achieved through bacterial fermentation (e.g., spoiled milk). Explain what is happening during this process. 6. A third method of curdling milk is by adding the enzyme rennin (chymosin). Most cheeses are made this way. Do some online research and explain how this protease enzyme works and why milk curdles when it's added. 7....
A chemist needs to make a buffer solution with a pH of 4.25 with a solution that currently contains 465 mL of 0.0941 M NaOH. The chemist plans to use acetic acid as the weak acid in the buffer. a) what should be the molar ratio of conjugate base to weak acid in the buffer solution? b) how many moles of acetic acid would need to be added to neutralize all of the sodium hydroxide? c) how many moles of...
a.) Given a 0.1 M solution of acetic acid and sodium acetate, describe how you would prepare 1.0 L of 0.1 M acetate buffer at a pH of 5.4 (the pKa of acetic acid is 4.75). Show all work. b.) With this new solution, what would the pH of the Buffer be when a 0.01 M solution of NaOH is added?
3. If acetic acid is not added to the TLC solvent, what effect would you predict that this would have on the Rf of ibuprofen? Why? 4. What are the four characteristics on an inflammatory response?
If you had stearic acid in a hexane solution and some of the hexane evaporated, what would happen to the Avogadro’s number and why? Thank you.
How much solid CH3COONa.3H2O should be added to 0.300 L of 0.500 M acetic acid solution to achieve a buffer of pH 5.25?
=Assume you have prepared 100.0 mL of a buffer solution using 0.400 mol of acetic acid (pKa = 4.74) and 0.400 mol of sodium acetate. The pH of this buffer solution is initially 4.74. After preparing this buffer solution, you added 55.0 mL of a 1.10 M NaOH solution to your buffer to see what would happen. What will the pH of this new solution be?
When a small volume of NaOH solution is added to an acetate/acetic acid buffer system, which of the following occur? Choose one or more: The final volume of the solution will increase The pH will increase. The pH will stay the same. The concentration of acetate will increase. The pH will decrease. The concentration of acetic acid will decrease.
1. If a solution of hydrochloric acid is added to a solution of sodium carbonate, what is observed? Write the net ionic equation of any reaction that may occur (4P). 2. You have a clear colorless unknown solution with a group I cation. After adding some hydrochloric acid solution you obtain a white precipitate. Addition of ammonia causes the white precipitate to dissolve. Acidifying with nitric acid makes the precipitate reappear. Which cation do you suggest was in the unknown...
