Marks: +1, -0
Mg can reduce NO3− to NH3 in basic medium.
NO3−+Mg(s)+H2O→Mg(OH)2(s) +OH−(aq.)+NH3(g)
A 25.0mL sample of NO3− solution was treated with Mg. The NH3(g) was passed into 100mL of 0.15NHCl. The excess of HCl required 32.10mL of 0.10N NaOH for neutralisation. What was the molarity of NO3− ions in the original sample? Give your answer after rounding off to two decimal places.
