Answer to Question #195352 in General Chemistry for Kyle

Question

A 10.0 mL solution is 0.50 M silver nitrate. What minimum volume (in milliliters) of 0.10M sodium acetate is required to ensure precipitation of silver acetate is required to ensure precipitation of silver acetate given that k_sp (AgCH₃COO) = 4.0x10^-3?

Answer 1

$AgNO_3 + CH_3COONa \to CH_3COOAg+ NaNO_3$

$K_{sp} = [Ag^+][CH_3COO^-]\\ 4.0×10^{-3}= [0.005][x]$

$x = 0.8M$

minimum volume (in milliliters) is 8ml.
