Part A: What is the pH of solution made by mixing 300ml of
0.120M H2SO4 with 185ml of 0.150M Sr(OH)2?
Part B: 250ml of 0.150M nitric acid is added to 300ml of 0.200M
Sulfuric (H2SO4) and then diluted up to 1.000L, what is the
resulting pH?
Part C: How much 0.440M solution of Nitric Acid is needed to
bring 22.1ml of 0.300M NaOH to neutrality?
What is the pH of the solution made by mixing 0.2 mol NaH2PO4
and 0.5 mol NaOH with water to make 1.00 L of solution? The pKa
values for H3PO4 are 2.12 7.20 and 12.
What is the pH of a solution made by mixing 500 mL of 1.00 M HCN
and 1.50 L of 0.250 M NaOH, and then diluting the entire solution
to a volume of 3.00 L? (Ka HCN = 4.0 x 10-10)

Calculate the pH of a solution that is made by mixing 0.80 L of
0.30 M formic acid (HCOOH, Ka=1.77X10-4) and 0.90 L of 0.20 M
sodium formate (NaHCOO). [Hint: don’t forget that you are mixing,
and so each is diluted upon mixing]
1. Calculate the pH of a solution that is made by mixing 0.80 L
of 0.30 M formic acid (HCOOH) and 0.90 L of 0.20 M sodium formate
(NaHCOO). Assume volumes are additive. (Ka, HCOOH = 1.77 * 10^-4
)
2. A 200.0 mL solution of 0.40 M ammonium chloride was titrated
with 0.80M sodium hydroxide. What was the pH of the solution after
50.0 mL of the NaOH solution were added? The Kb of ammonia is 1.76
* 10^-5...
