Question

Cabr2 will most likely dissolve in which solvent? 1. bi3 2. h2o 3. br2 4. ccl4 5. c8h18

Answer 1

General principle of solubility is 'like dissolves like'

$CaBr_{2}$ is an ionic compound, wherein the constituent ions ($Ca^{2+}$ and $Br^{-}$) are held by electrostatic forces of interaction. 

Such ionic compounds are soluble in polar solvents. 

Among the solvent mentioned in question, water ($H_{2}O$) has maximum polarity. Hence, $CaBr_{2}$ is most likely to dissolve in $H_{2}O$
