Zn can reduce to in basic solution. (The following equation is not balanced.) The can be neutralized with an excess of HCl(aq). Then, the unreacted HCl can be titrated with NaOH. In this way a quantitative determination of can be achieved. A25.00 mL sample of nitrate solution was treated with zinc in basic solution. The was passed into 50.00 mL of 0.1500 M HCl. The excess HCl required 32.10 mL of 0.1000 M NaOH for its titration. What was the in the original sample?
