JEE Main Chemistry question
In acid medium Zn reduces nitrate ion to ion according to the reaction
Zn + → + + (unbalanced)
How many moles of HCl are required to reduce half a mole of completely? Assume the availability of sufficient Zn.
Answer: (A)
Solution
The balanced equation is 4Zn + NO_3^- + 10H^+ \to 4Zn^{2+} + NH_4^+ + 3H_2O, so 1 mole of requires 10 moles of
