Question
To measure the concentration of an aqueous solution of H,0,, an analytical chemist adds strong acid to a 48.00 g sample of the solution and titrates it to the endpoint with 361. mL of 0.150M potassium permanganate (KMNO,) solution. The balanced chemical equation for the reaction is: 6H¨ (ag) + 5H,0,(ag) + 2MnO,(aq) → 50,(2) + 2Mn²*(aq) + 8 H,0 (1) O precipitation What kind of reaction is this? O acid-base O redox If you said this was a precipitation reaction, enter the chemical formula of the precipitate. If you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base. If you said this was a redox reaction, enter the chemical symbol of the element that is oxidized. Calculate the mass percent of H,0, in the sample. Be sure your answer has the % correct number of significant digits.
