NaNO3 solubility in HNO3?

Question

Can someone show me the solubility curve of Sodium Nitrate at different molarities of Nitric Acid or a relationship between the two

Answer 1

I'm on holiday, and don't have tables handy, but----maybe this will show you where to start.

If you can find a solubility curve for NaNO3 in pure water, you can figure out how many moles of NaNO3 will dissolve at a specific temperature  (moles NaNO3 = mass of NaNO3 divided by molar mass of NaNO3).

The solubility of sodium nitrate will be less in a solution of nitric acid than in pure water, because of the common ion effect (both have NO3-)

If all solubilities are in mol/L,  then

solubility of NaNO3 in HNO3 = (solubility of NaNO3 in pure water) - (concentration of HNO3)  [if all solutions are at the same temperature]
