When a copper wire added to HCI No reaction observed, because copper considered as Inactive metal. 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 became which indicates the presence of ion, thus,Cu was to Cu2. The reaction was done in the fume hood because NO2 gas is Cu (s) + HNO3 (aq) → 4. When sodium oxalate was reacted with KMNO4, the color of the solution was changed from to due to the of MnOa to KMNO4 act as a strong agent in acidic media, so was added to the…
