AP Chem Balancing Practice
• A solution of nickel (II) chloride is added to
a solution of sodium hydroxide, forming a
precipitate.
– Write the balanced net ionic equation.
– If equal volumes of 1.0 M nickel (II) chloride
and 1.0 M sodium hydroxide are used, what
ion is present in the solution in the highest
concentration after the precipitate forms?
