Question
Citric acid (H3Cit) can be used as a household cleaning agent to dissolve rust stains. The rust, represented as FeOH3, dissolves because the citrate ion forms a soluble complex with Fe3+: Fe(OH)3 (s) + H3Cit (aq) -> Fe(Cit) (aq) +3H20 (l) Citric acid Has Ka1: 7.1 * 10^(-4), Ka2: 1.7 * 10^(-5), Ka3: 4.1* 10^-7 Kf H3Cit : 6.3 *10^11 1) Calculate the equilibrium constant for the above reaction 2) Calculate the molar solubility of Fe(OH)3 in a 0.555M solution of H3Cit Please Help! Thank you so much!!!Explanation / Answer
