#### Answer

Soluble; $K^+$ and $CH_3COO^-$

#### Work Step by Step

In order to find whether or not the substance is soluble in water, use the solubility rules. Using this, we obtain that the substance is soluble in water. In order to find which ions are present, look for the cations (positive ions) and anions (negative ions) in the given substances. Recall, you may have to consider polyatomic ions, which are ions with multiple atoms that you need to memorize.
