To measure the concentration of an aqueous solution of H₂O,, an analytical chemist adds strong acid to a 34.00 g sample of the solution and titrates it to the endpoint with 61.3 ml. of 0.450M potassium permanganate (KMnO,) solution. The balanced chemical equation for the reaction is: 6H (aq) SH₂O₂ (aq) 2MBO (og) + What kind of reaction is this? - 50,(eg) + 2Mn (aq) + SH₂O(0) 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 H₂O, in the sample. Be sure your answer has the correct number of significant digits. O precipitation O acid-base redox 0 0 O 0% q X 8 3

Question
To measure the concentration of an aqueous solution of H₂O₂, an analytical chemist adds strong acid to a 34.00 g sample of the solution and titrates it to the andpoint with 61.3 ml. of 0.450M potassium permanganat (KMnO,) solution. The balanced chemical equation for the reaction is: 6H (aq) + SH₂O₂(aq) + What kind of reaction is this? 2MBO (ag) 50,(g) + 2Mn (aq) +8H₂0 (1) - 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 H₂O, in the sample. Be sure your answer has the correct number of significant digits. O precipitation O acid-base redox 0 0 0% X Co 0.2 S
