PART A)
A solution is prepared by mixing equal volumes of 0.17 M HCl and 0.42 M HNO3. (Assume that volumes are additive.) Express the pH to two decimal places.
PART B)
Using the chart Estimate [H3O+] in a 1.5 M solution of each acid.
Express the molar concentrations to two significant figures separated by commas.
I'm stuck on the one that says very large. For all the other ones I multiplied the Ka by the 1.5M. The answer for the large one is NOT "verylarge" 1.5 or 0. Please help!
| Acid | Formula | Ka |
| Formic | HCO2H | 1.8×10−4 |
| Hydrocyanic | HCN | 4.9×10−10 |
| Perchloric | HClO4 | very large |
| Hypobromous | HOBr |
2.0×10−9 |

Question 6
Calculate the pH of a solution prepared by mixing equal volumes
of 0.050 M sodium oxalate, Na2C2O4 (aq), and 0.010 M
ammonium chloride, NH4Cl (aq).
For ammonium, Ka = 5.70 × 10–10; for oxalic acid,
Ka,1 = 5.60 × 10–2and Ka,2 = 5.42 × 10–5.
Hint #1: Use the charge balance
equation as your main equation. Use the mass balance and
equilibrium equations to find an expression for each species in
terms of [H3O+] or [OH–], then substitute...

what is the pOH of a solution prepared by mixing 0.01 moles of
HCL with 25.00 mL of 1.0 methylamine, CH3NH2, and with 15.00 mL of
1.0 M methylammonium chloride, CH3NH3CL? Assume that the volume of
the solutions are additive and that Kb= 3.70 x 10^-4 for
methylamine. You cant use the Henderson-Hasselbalch equation in
solving this problem.

Equal volumes of a 0.020 M Zn^2+ solution and a 2.0 M NH3
solution are mixed. Kf for [Zn(NH3)4]^2+ is 4.1 × 10^8. If
enough sodium oxalate is added to make the solution 0.10 M in
