The addition of a measured amount of a solution of one reagent (called the titrant) from a burette to a definite amount of another reagent (called analyte) until the reaction between them is complete, i.e., till the second reagent (analyte) is completely used up, i.e., up to end point. (c) An element in a compound can function as an oxidizing agent as well as reducing agent if it is in its intermediate oxidation state. A reducing agent after carrying out reduction is itself oxidised in a chemical reaction. It always occurs in coexistence with the oxidation reaction only. of an element is = Group no. The reaction taking place in batteries are redox reactions. Get notified about the latest career insights, study tips, and offers at Leverage Edu.
