9). What is the balanced equation for the acid–base reaction of nitrous acid with lithium hydroxide?

Question

LiOH(aq) + HNO3(aq)  H2O(l) + LiNO3(aq)
Li(OH)2(aq) + 2 HNO3(aq)  2 H2O(l) + Li(NO3)2(aq)
LiOH(aq) + HNO2(aq)  H2O(l) + LiNO2(aq)
2 LiOH(aq) + H2NO2(aq)  2 H2O(l) + Li2NO2(aq)

Answer 1

Nitrous acid is HNO2
