Question #9bb2f

Answer 1

Beryllium forms a 1:1 salt with sulfate anion, to form `BeSO_4`. First, we must review actual solubilities.

Explanation:

This source lists the aqueous solubilties per 100 mL as follows:

`0""^@C: 36.2*g`;
`20""^@C: 40.0*g`;
`60""^@C: 54.3.*g`;

Let's compare this with magnesium sulfate, `MgSO_4`:

`0""^@C: 26.9*g`;
`20""^@C: 35.0*g`;
`60""^@C: 50.2*g`;

The moral, beryllium sulfate has a comparable solubility to its magnesium analogue.

Of course, general solubility rules holds that all sulfates are soluble, EXCEPT for lead, silver, and barium.
