Question

3.a)Define activity series of metals. Arrange the metals gold,

copper, Iron and magnesiuminorder of their increase in

reactivity.

b)What will you observe when:

i)Some zinc pieces are put in copper sulphate solution​

Answer 1

Answer:

Here it is

Explanation:

A) In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.

Most reactive to least As your Question is

Magnesium

Iron

Copper

Gold

B) When zinc pieces are put into blue colour copper sulphate solution, Zinc displaces copper from copper sulphate solution. In this process, blue copper sulphate solution turns into colourless. No reaction, As Cu is less reactive than iron.
