# Relationship of $K_b$ to Solubility in Basic Solution

CHEM-ALKA4Y

You are given two salts, $\textrm{XCl}$ and $\textrm{YCl}$. $\textrm{X}$ and $\textrm{Y}$ are unknown cations. $\textrm{XCl}$ and $\textrm{YCl}$ have similar $K_{sp}$ values.

Given that the $K_b$ of $\textrm{XOH}$ is much greater than the $K_b$ of $\textrm{YOH}$, which of the salts is more soluble in base?

A

$\textrm{XCl}$

B

$\textrm{YCl}$

C
