Two chemical reactions are carried by adding sodium hydroxide to the acidic solution from Part I. During the first reaction is the neutralization of the excess of nitric acid in the mixture by sodium hydroxide. The second reaction takes the place after naturalization is a complete and NaOH is in excess. While the liquid inside the beaker is being stirred, with the stirring rod, 10 ml of 6 M NaOH is poured into the solution from Part I at 1 mL at a time. After each 1 mL the solution is tested for acidity with red litmus paper. When the litmus paper final appear blue, the stirring is stopped and no more 6 M NaOH is added into the beaker. After each addition of 6 M NaOH the solution in the beaker becomes a thicker and darker
