Q.1) pH 1 = 2.4 [H+]= 0.0039M
pH 2 = 2.7 [H+] = 0.00199M
We know M1V1 +M2V2 = M3(V1+V2) ==>M3= 0.0028M
pH = -log [H+] = 2.55
Q.2) Molarity= number of moles×1000/volume in mL ==>M= 5.15×1000/241.86×150 = 0.142M

A student prepares a 100.0-mL buffer solution that is 0.200 M in hydrofluoric acid and 0.200 M in sodium fluoride. How many grams of sodium hydroxide should be added to the buffer solution to change its pH to 4.00? (Assume no volume change upon adding the sodium hydroxide). I'm seeking the detailed work in finding the solution to this problem. Many thanks!
Identifying weak acid values Data A student is trying to identify a weak acid by measuring the pH of partially neutralized weak acid solutions. In the lab the student is preparing three solutions by adding 5.00 ml, 10.00 ml, and 15.00 mL of a 0.200 M NaOH solution to 10.00 mL of 0.500 M weak acid solution.
