Question

Write balance net ionic equations for the following reactions: a) Iron (II) sulfide dissolves in aqueous hydrochloric acid. b) A solution containing iron (III) ion is treated with ammonia solution. c) Iron (III) hydroxide dissolves in hydrochloric acid solution. d) Barium carbonate dissolves in acetic acid solution. The solubility of KNO_3 is given as 32.0 g per 100. mL of solution a N, and O are 39.098 g/mol, 14.007 g/mol, and 15.999 g/mol, respectively. a. What are the molar concentrations of K^+ and NO_3^- in a saturated solution temperature? b. Calculate Ksp for KNO_3 at this temperature. [K^+] =

Explanation / Answer
