An 8mL sample of an unknown concentration of NH3 is titrated with HCl. It is found that 12mL of 0.10M HCl is required to reach the equivalence point.
What was the concentration of the NH3 in the initial 8mL sample?
Also what would be the pH be when 6mL of 0.10M Hcl is added to the initial 8mL sample of NH3?
