Problem: Which of the following ions will react with water in a hydrolysis reaction:K +, Ba2+, Cu2+, Zn2+, F-, SO32-, Cl-For those ions that undergo hydrolysis, write net ionic equations for the hydrolysis reaction.

FREE Expert Solution

Hydrolysis is simply the reaction with water. 

  • Ions from strong acids and bases would not react with water. 
  • Ions of strong bases (combined with OH-):  K +, Ba2+ 
  • Ions of a strong acid (combine with H+): Cl-


For the net reactions of the remaining ions:

  • For cation(positive): Product = Cation(OH) + H+
  • For anion (negative) : Product = H(Anion)+ OH-

Take note to Crisscross (charge to the subscript of other ion) the charges to identify the proper ratio of ions in the compound.
