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: 2kmno4(aq)+h2o2(aq)+3h2so4(aq)→3o2( g)+2mnso4(aq)+k2so4(aq)+4h2o(l) a certain amount of hydrogen peroxide was dissolved in 100. ml of water and then titrated with 1.68 m kmno4. how much h2o2 was dissolved if the titration required 14.3 ml of the kmno4 solution?

0.408 g amount of hydrogen peroxide was dissolved in 100 mL of water.

Explanation:

Molarity of the solution = 1.68 M

Number of moles of ,n = 0.0240 moles

According to reaction 2 moles of reacts with 1 mole of , then  0.0240 moles of KMnO_4 will react with : moles of that is 0.0120 moles

Mass of =0.0120 moles × 34 g/mol=0.408 g

0.408 g amount of hydrogen peroxide was dissolved in 100 mL of water.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
