Question

question 4 (1 point) which of the following two compounds could be your hydrated ionic compound? a) caso₄·2h₂o b) beso₃·4h₂o

Explanation:

To determine the hydrated ionic compound, we analyze the stability of the ions. Calcium (Ca²⁺) forms stable compounds with sulfate (SO₄²⁻), and \( \text{CaSO}_4 \cdot 2\text{H}_2\text{O} \) (gypsum) is a well - known hydrated ionic compound. Beryllium (Be²⁺) with sulfite (SO₃²⁻) is less common as a stable hydrated ionic compound in typical contexts, and the combination is not as well - established as the calcium sulfate hydrate.

Answer:

A) \( \text{CaSO}_4 \cdot 2\text{H}_2\text{O} \)
