I want to use metal oxide and acid to make soluble metal salt, nitrate, sulphate and chloride which best?

What metal? what oxide? what concentration acids? what is the resulting salt going to be used for? The question has no info whatsoever.

Looks like a homework question to me.

Many metal oxides, like iron, nickel, copper, zinc. I think acid can be any concentration. I want to use soluble salts to grow crystals and make
insoluble salts. the page can't open.

Sulphates are generally better for growing crystals.

Sulphates are very good for growing crystals (especially double sulfates). Some chlorides also have nice crystals (MnCl2 grows in nice purple cubes).
For making insoluble salts it mostly doesn't matter which you choose. Sulfates, nitrates and perchlorates are good for making complexes, because
anions are weakly coordinating. Of course if you want to make chloro complex, metal chloride is first choice.

Try copper sulfate pentahydrate, makes really nice blue crystals
