Consider a solution formed by mixing 50.0 mL of 0.100 M H2SO4, 30.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ba(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution.

A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has this condition, her doctors take a 0.01534 L sample of her gastric juices and titrate the sample with 0.000185 M KOH. The gastric juice sample required 0.00645 L of the KOH titrant to neutralize it. Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise interfere with the titration.

Calculate the pH of the solution after 433 mL of 0.561 M HCl is added to 2.43 L of a solution that is 0.226 M HC2H3O2 and 0.416 M KC2H3O2. Ka for HC2H3O2 is 1.8x10^-5

You have 50.00 mL of a solution that is 0.100 M in aceticacid, and you neutralize it by adding 50.00 mL of a solution that is 0.100 M in sodium hydroxide. The pH of the resulting solution is not 7.00. Explain why. Is the pH of the solution greater than or less than 7?

Calculate the pH of a solution formed by adding 8.00 grams of solid sodium azide, NaN₃, to 210.0 ml of 0.230 M hydrazoic acid solution, HN₃. You may assume that the salt dissolves completely and that the change in volume is negligible upon addition of the solid.

Calculate the pH of a solution made by mixing 200 mL of 0.100 M potassium formate with 50.00 mL of 0.15 M hydrochloric acid.

Calculate the pH of a solution that is 0.155 M in acetic acid and 0.255 M in sodium acetate. The Ka of acetic acid is 1.8 x 10^-5.

Calculate the pH of a solution formed by mixing 120.0 mL of 0.30 M HClO with 1180.0 mL of 0.20 M LiClO. The Ka for HClO is 2.9 × 10-8. I tried using the Henderson Hasselbalch equation which gives me 8.35 but that's not one of the possible answers. It has to be 7.06, 7.54, 7.46, or 5.99

determine the pH of the resulting solutions when the 2 reagents are mixed together. 25.00 mL of 0.2500M HCl and 12.00mL of 0.2500M NaOH 35.00 mL of 0.100M NaOH and 25.00mL of 0.125M HBr 15.00mL of 0.2500M HF and 5.00mL of 0.2000M NaOH

5.0 ml of 0.0500M Sr(OH)2 solution is combined with 75.0 ml of 0.0600M LiOH solution.  Calculate the pH of the resulting mixture
