When a copper wire added to HCI No reactionobserved, because copperconsidered asInactivemetal.3. Then, in fume hood 6 M HNO3 was added to a piece of copper wire.gas was formed, And the color of the solution becamewhich indicates thepresence ofion, thus,Cu wasto Cu2. The reaction was done inthe fume hood because NO2 gas isCu (s) + HNO3 (aq) →4. When sodium oxalate was reacted with KMNO4, the color of the solution was changedfromtodue to theof MnOa toKMNO4 act as a strongagent in acidic media, sowas addedto the test tube to provide anmedia for the reaction.Balanced equation in acidic media : 2 MnO, + 16 H* + 5 C20. → THIS EQUATION NOT REQUIRED
