Hello,

Question

If I add water to a solid, how do i represent it in a equation with phases?

for example the NaNO3 was the solid in this case and H2O was the liquid,

does NaNO3 turns into an aqueous or stays as solid when I write the equation?

Which one would be correct?
1) NaNO3(s) + H2O(l) = HNO3(aq) + NaOH(aq)
or
2)NaNO3(aq) + H2O(l) = HNO3(aq) + NaOH(aq)

Thanks!

Answer 1

it is in aq phase when it reacts:

NaNO3(aq)+...

Answer 2

I don't understand how it turns into aq when its a solid I add into the water, isn't only the products turn into aq?

Answer 3

nope, once dissolved, it is in aqueous solution.

Answer 4

So despite having to shake the test tube for it to dissolve into the water, NaNO3 in this case would be considered as Aqueous?
