1. The acid HA has pKa = 6.5, what is the quotient[A-]/[HA] at pH 7.00 ?
2. Titration of 25.00mL of 0.1005 M KI with 0.05124 MAgNO3. Calculate pAg at the volume of adding 35.00 mL ofAgNO3. Ksp (AgI) = 8.3x10-17.
3. What is the pH if 0.020 0 mol of HA (with pK a =2.00) and 0.020 0 mol of A− are dissolved in waterto make 1.00 L of solution? Need to consider that HA in this caseis a relative strong acid.
