What is the concentration of H3O+ in a buffered solution made by adding 0.30 mol of acetic acid and 0.30 mol of sodium acetate to enough water to make 1.0 L of solution? The chemical reaction is: CH₂COOH(aq) ⇒ H+ (aq)+CH₂COO¯(aq) Ka for this reaction is 1.8 x 10-5. (NOTE: write an ICE table on a sheet of paper) (A) 0.30 M (B) 1.8 x 10-5 M (C) 10-7 M (D) 10-14 M (E) this is a weak acid with a lot of common ion so 0.0 molar.
