Can we distinguish between zinc nitrate and calcium nitrate by just a one step reaction with each one of them?

And also i want know about the solubility of barium chloride in acids??

Question-
Which anion is present in the salt solution which reacts with barium nitrate to give a white ppt. soluble in nitric acid and not soluble in sulphuric acid??
My attempt -
Chloride
As it will react to produce Barium chloride which is very much soluble in nitric acid but is it soluble in sulphuric acid???

Barium chloride is well soluble, so it is not a good idea. What INSOLUBLE salts of barium do you know?

[Kartiky14]

Barium Sulphate..
But I know that only its insoluble in HCl and HNO3.....i have no idea about H2SO4?(I have read it somewhere it is not soluble in mineral acids...but i'm not sure about "All" mineral acid which includes H2SO4 )

[Borek]

As far as I know barium sulfate doesn't dissolve in mineral acids. Perhaps question tries to be tricky - perhaps what it means is that there is still precipitate present in the solution after the reaction ends.

Well in the entire question, (the thing i posted is just a part of it) we have to choose from a list of anions, so it was quite easy as sulphate only stands correct in this part....was just curious to know about its solubility in H2SO4(what-if-the-list-wasn't-given-precaution) Thanks a bunch !!
