Determine the solubility of iron (in mg/L as Fe) in a solution in equilibrium with Fe(OH)3 (s), Iron(III) hydroxide 10^-2M total sulfate (SO4^-2) and a pH of 7?
Using a sample of impure Sodium carbonate, of 0.3240 grams was mixed in 50.00mL of 0.1280 M Hydrochloric acid. The excess acid then needs 30.10 mL of 0.1220 M sodium hydroxide for complete neutralization. Compute the % sodium carbonate (MM = 105.99 g/mol) in this sample.
