Calculate the concentration of the hydronium ion and then the pH in a solution that is formed by combining 300mL of 0.10 M Ca(OH)2 with 300mL of 0.10 M H2SO4? (Ka2 = 1.2 x 10^-2 for sulfuric acid). Ca(OH)2(aq) + H2SO4(aq) <---> CaSO4(aq) + 2H2O
A 30.00mL sample of 0.1234M hypobromous acid (HBrO) is titrated with a 0.2555M potassium hydroxide solution. (Ka for hypobromous acid = 2.5x10^-9) How many milliliters of potassium hydroxide solution would be required to reach the midpoint of the ..
