Question

In the experiment of reaction of solution of copper sulphate with iron nail,speed of reaction increases if we use iron wire scrubber instead of iron nail.Which factor do u observe that affects the rate of reaction?Explain.

Answer 1

That's copper. When Iron nail (Ferrum) is dipped in Copper sulphate (CuSO4) there takes reaction between them and coppersulphate change its color from blue to light green. This shows Iron is more reactive than Copper, it can replace Copper from CuSO4.
