Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. for example, a solution of hydrogen peroxide, h2o2, can be titrated against a solution of potassium permanganate, kmno4. the following equation represents the reaction: 2 kmno4 (aq) + h2o2 (aq) + 3 h2so4 (aq) → 3 o2 (g) + 2 mnso4 (aq) + k2so4 (aq) + 4 h2o (l) a certain amount of hydrogen peroxide was dissolved in 100. ml of water and then titrated with 1.66 m kmno4. what mass of h2o2 was dissolved if the titration required 13.2 ml of the kmno4 solution?

0.374 g

Explanation:

Hello,

Since both the molarity and the volume allows us to know the moles of potassium permanganate, and we already have the balanced chemical reaction, the stoichiometric procedure that is attached in the picture, is developed to substantiate the the titrated mass of hydrogen peroxide was 0.374 g.

Best regards.

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl

what is the question here. i think you messed up.
