The solubility of CsBr 3 ​ in water is 746 ppm . Assuming the density of solution is 1 g / cc the solubility product of CsBr 3 ​ is

TestHub · Accepted Answer

∵ Solubility is 746 ppm.

∴ solubility in g/L = 0.746.

∴ $S o l u bi l i t y = \frac{0.746}{373} = 2 \times 1 0^{- 3} m o l / L$

$C s B r_{3} (s) ⇌ C s^{+} (a q) + B r_{3}^{-} (a q)$

$K_{s p} = [C s^{+}] [B r_{3}^{-}] = (2 \times 1 0^{- 3}) \times (2 \times 1 0^{- 3}) = 4 \times 1 0^{- 6} M^{2}$
