What is the [h3o+] and the ph of a benzoic acid-benzoate buffer that consists of 0.17 m c6h5cooh and 0.42 m c6h5coona? (ka of benzoic acid = 6.3 × 10^−5). be sure to report your answer to the correct number of significant figures.

According to the balanced chemical equation 5 h2c2o4(aq) + 2 mno4-(aq) + 6 h+(aq) → 10 co2(g) + 2 mn2+(aq) + 8 h2o(l) 0.875 grams of oxalic acid, h2c2o4 will react with moles of permanganate, mno4-.
