Question

2/15
which of the following compounds is soluble?
strontium carbonate
potassium carbonate
calcium carbonate

Explanation:

Solubility rules state that carbonate compounds are generally insoluble in water, except when paired with group 1 alkali metals (like potassium). Strontium and calcium are group 2 metals, so their carbonates are insoluble, while potassium carbonate (a group 1 carbonate) is soluble.

Answer:

potassium carbonate
