1. What are the values for the pH, POH, [H*], and [OH-] for a solution made by mixing 10 mL of 1.5 HCl (a strong acid) with 10 ml of 1.2 M NaOH (a strong base)? (Hint: Determine the volume for the equivalence point first and then figure out if you are before or after the equivalence point) 2. What are the values for the pH, POH, [H*], and [OH-] for a solution made by mixing 10 mL of 1.5 HCl (a strong acid) with 12.5 mL of 1.2 M NaOH (a strong base)?
