1 a Good conductors of electricity

2 II Two and three only

3) a Reacts with water to form hydrogen ions

4) d 2 x 10^-2M

HNO3(aq) → H+(aq) + NO3-(aq)

HNO3 is a monoprotic acid(giving a single proton on dissociation) and hence the H+ ion concentartion on dissociation of the acid is same as the concentration of the acid used.
