Solubility of Carbonates and Ions

The video explores the solubility of strontium carbonate (SrCO3) in water. It begins by discussing general solubility rules, highlighting that most carbonates are insoluble except for those of group 1 elements and ammonium carbonate. The video then uses a solubility table to confirm that SrCO3 is indeed insoluble in water, with only a negligible amount dissolving. The conclusion reiterates that SrCO3 is insoluble, aligning with the solubility rules and table findings.

What is the general solubility rule for carbonates?

• Carbonates are soluble only in hot water.

• Most carbonates are insoluble, with some exceptions.

• All carbonates are soluble.

• Carbonates are always insoluble.
