Metals React With Other Metal Salts
Metals React With Other Metal Salts
Displacement Reactions:
In a displacement reaction, a metal reacts with a salt solution and ‘displaces’ (or replaces) the metal present in it. Displacement reactions are explained on the basis of the activity series of metals. The activity series of metals is a list of common metals arranged in the decreasing order of reactivity. This means that a metal which is placed higher in the activity series is more reactive than those placed below it.
A metal will only react with a salt solution if it is placed higher in the activity series than the metal in the salt. For example, iron, which is placed higher in the activity series than copper, reacts with copper sulphate solution.
Silver does not react with zinc sulphate.
Zinc reacts with copper sulphate to form zinc sulphate and copper.
Which of the following are correct : (a) Magnesium and zinc do not displace copper from copper sulphate solution. (b) Magnesium and zinc displace copper from copper sulphate solution. (c) Aluminium and iron displace copper from solution of copper sulphate. | |||
