1(a)A solution that is formed by combining 400 mL of 0.025 molar HCl with 600 mL of 0.015 molar NaOH has a pH of_______ ? Please, can u explain to me hoe to do it?
(b)What is the pH of a solution which is 0.0100 M in HA and also 0.0020 M in NaA (Ka = 9.0 * 10-6)?
I think answer is 5.65, is that correct?
(c)A sample of ammonia (Kb = 1.8 * 10-5) is titrated with 0.1 M H2SO4. At the equivalence point, the pH is approximately______ ?
I think 5 not too sure.
Here is the solution... View the full answer
