To find the solubility of calcium iodate (Ca(IO3)2) in grams per liter at 18°C, we will follow these steps: ### Step 1: Write the dissociation equation Calcium iodate dissociates in water as follows: \[ \text{Ca(IO}_3\text{)}_2 \rightleftharpoons \text{Ca}^{2+} + 2 \text{IO}_3^{-} \] ### Step 2: Define molar solubility Let the molar solubility of calcium iodate be \( S \) (in moles per liter). When 1 mole of calcium iodate dissolves, it produces: ...
