Ammonium chloride solutions are slightly acidic, so they are better solvents than water for insoluble substances such as Ca(OH)₂. Identify two reactions that, added together, give the overall reaction below, and determine K_c for the overall reaction.
Ca(OH)₂(s)+ 2NH₄⁺(aq) Ca²⁺(aq)+ 2NH₃(aq)+ 2H₂O
Given: K_sp for Ca(OH)₂ is 4.0 * 10^-8; K_b for NH₃ is 1.8 * 10^-5.
