Question

On the basis of the reactivity of metals, predict how these metals will react with each of the salt solution
Metals: magnesium, zinc, copper, iron, potassium
salt solution: Magnesium Sulphate, zinc sulphate, copper sulphate, iron sulphate, and potassium sulphate

Answer 1

metals form respective salts what react with dilute acid.
Metal+dil.acid=metal salt+hydrogen
ex:2Na+2HCL=2Nacl+H2
2K+H2SO4=K2SO4+H2

Answer 2

Answer:

Increasing order of metal of their reactivity.

Copper < iron < zinc < magnesium

Two observations are as :

1. Color of the solution changes from blue to green

2. Reddish brown deposits on iron filings.
