Mixtures of CaCl₂ and NaCl are used to melt ice on roads. A  dissolved 1.9348-g sample of such a mixture was analyzed by using excess Na₂C₂O₄ to precipitate the Ca²⁺ as CaC₂O₄. The CaC2O₄ was dissolved in sulfuric acid, and the resulting H₂C₂O₄ was titrated with 37.68 mL of 0.1019 M KMnO₄ solution.
(c) What is the oxidizing agent?

Respuesta :

Balanced net ionic equation for precipitation reaction.

Ca2+ + C202 -> CaC204

Balanced net ionic equation for titration reaction.

6H+ + 5H2C2O4 + 2MnO4 210C02+ 2Mn2++8H20

Oxidizing agent = KMnO4

What is Oxidizing agent ?

A substance that has the ability to oxidize other substances or in other words, a substance that has the ability to give oxygen or replace hydrogen on reaction with other compounds are called oxidising agents . Example : oxygen, halogens etc.

  • Common examples of oxidizing agents include halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide (H2O2)
