please confirm these!!! will be sure to rate your answer :) a) b) Question 3 Part...
Suppose you have created a buffer solution that is 0.250 M in both benzoic acid (HC7H5O2) and potassium benzoate (KC7H5O2) and that the pH of this solution is 4.65. Assuming that the buffer capacity has not been exceeded, which of the pH values listed below would you expect after adding a small amount of a dilute strong acid solution? 8.85 4.49 4.81 2.88 There is not enough information to determine.
Suppose you have created a butter solution that is 0.250 M in both benzoic acid (HC,H,O,) and potassium benzoate (KCH,0z) and that the pH of this solution is 465. Assuming that the butter capacity has not been exceeded, which of the pH values listed below would you expect after adding a small amount of a dilute strong acid solution? O 4.49 4.81 8.85 2.88 There is not enough information to determine
Please help. The answer to this question has been wrong both times I have submitted it on here. I really need to understand this. Assume you dissolve 0.175 g of the weak acid benzoic acid, CH, CO,H, in enough water to make 1.00 x 102 mL of solution and then titrate the solution with 0.182 M NaOH. K, for benzoic acid = 6.3 x 10-5.) CH3CO, H(aq) + OH(aq) = CHCO2 (aq) + H2O(C) What was the pH of the...
Please explain all steps ledgibly the highlighted part is the answer 11. A 500.0 mL buffer solution is 0.10 M in benzoic acid and 0.10 M in sodium benzoate (Ka 6.4 x 109) and has an initial pH of 4.19. What is the pH of the bu Fer upon addition of 0.010 mol of NaOH (assume no volume increase). (1) 1.70 (2) 4.01 (3) 4.28 4)7 (5) 4.51
please answer ALL parts of this one question. (a,b and part c). do not answer if you will not answer them all please. Use the References to access important values if needed for this question. A 1.00 liter solution contains 0.48 M acetic acid and 0.36 M sodium acetate. If 35.0 mL of water are added to this system, indicate whether the following statements are true or false. (Note the the volume MUST CHANGE upon the addition of water.) A....
this is part a and b of one question. please answer all parts or leave to another tutor. Use the References to access important values if needed for this question. A 1.00 liter solution contains 0.35 M ammonia and 0.45 M ammonium nitrate. If 0.110 moles of calcium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of calcium hydroxide.) A. The number of...
