solubility

Question 1

Are all Group 1 salts soluble?

Answer 1

Yes — all Group 1 metal salts are soluble, no exceptions.

Question 2

Are ammonium (NH₄⁺) salts soluble?

Answer 2

Yes — all ammonium salts are soluble.

Question 3

Are all nitrates (NO₃⁻) soluble?

Answer 3

Yes — all nitrates are completely soluble.

Question 4

Are chlorides, bromides, and iodides generally soluble?

Answer 4

Yes — except for Ag⁺ and Pb²⁺ salts (e.g. AgCl, PbI₂ are insoluble).

Question 5

Are all sulfates soluble?

Answer 5

Most are, but BaSO₄, PbSO₄, CaSO₄, SrSO₄ are insoluble or only slightly soluble.

Question 6

Are carbonates generally soluble?

Answer 6

No — only Group 1 and ammonium carbonates are soluble.

Question 7

Are phosphates (PO₄³⁻) soluble?

Answer 7

No — only soluble with Group 1 and NH₄⁺.

Question 8

Give the solubility of hydroxides
- Group 1
- Group 2
- Transition metals
-Al(OH)3

Answer 8

All group 1 hydroxides are soluble

All group 2 hydroxides are soluble except Mg and Be

Most transition metals are insoluble in water

Al(OH)3 is insoluble in water but soluble in NaOH
