Ammonium Chloride Solutions Are Slightly Acidic, So They Are Better

Question 130

Essay

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 when added together, give the overall reaction below, and determine Kc for the overall reaction.
Ca(OH)2(s)+ 2NH4+(aq) Ammonium chloride solutions are slightly acidic, so they are better solvents than water for insoluble substances such as Ca(OH)<sub>2</sub>.Identify two reactions that when added together, give the overall reaction below, and determine K<sub>c</sub> for the overall reaction. Ca(OH)<sub>2</sub>(s)+ 2NH<sub>4</sub><sup>+</sup>(aq) <sub> </sub> Ca<sup>2+</sup>(aq)+ 2NH<sub>3</sub>(aq)+ 2H<sub>2</sub>O Given: K<sub>sp</sub> for Ca(OH)<sub>2</sub> is 4.0 × 10<sup>-8</sup>; K<sub>b</sub> for NH<sub>3</sub> is 1.8 × 10<sup>-5</sup>.
