In which aqueous solution will the most zns dissolve?

1)0.1 m nacl
2)0.1 m zn(no3)2
3)0.1 m (nh4)2s
4)0.1 m mgs

1) NaCl 0.1 M

Explanation:

It will dissolve more in the aqueous NaCl solution.

All other solutions have a common ion with salt.

They will saturate faster by the effect of the common ion.

The effect of the common ion occurs when the elements that make up the solute are present in the aqueous solution.

As in the solution, there is already a certain amount of the element the solution will tolerate less solute and will precipitate faster under these conditions, unlike we add this same amount of solute in a solution that does not contain any element of the solute.

the answer is definitely c.
