Question

using the solubility rules given, predict if the ionic compound coco₃ is soluble in water or insoluble. select one: soluble insoluble

Explanation:

To determine the solubility of \( \text{CoCO}_3 \) (cobalt(II) carbonate) in water, we use solubility rules. Carbonates (\( \text{CO}_3^{2-} \)) are generally insoluble in water, except for those of alkali metals (Group 1) and ammonium (\( \text{NH}_4^+ \)). Cobalt (Co) is a transition metal, not an alkali metal or ammonium. Thus, \( \text{CoCO}_3 \) follows the general rule for carbonates and is insoluble.

Answer:

Insoluble (the option labeled "Insoluble")
