Question

24) Four Metals are arranged according to the decreasing tendency of liberating hydrogen gaš from délute acid ca, zn, fe, (h), cu. in which of the following cases will a precipitate of the less reactive metal be obtained?
when zinc is added to an aqueous solution of copper sulfate.

when iron is added to an aqueous solution of calcium chlorine.

when copper is added aqueous solution of calcium chlorine.

when iron is added to an aqueous solution of zinc sulfate.​

Answer 1

Answer:

a) Generally, non-metals react with acid →False

b) Sodium is a very reactive metal →True

c) Copper displace zinc from zinc sulphate solution →False

d) Coal can be drawn into wire →False.

Note:

(a) Metals react with acid because metals are Eierro positive, ∴ metals can give e

⊖

to hydrogen gas while non-metals not

(c) Zinc is more reactive metal and Hence it displaces copper from copper sulphate solution.

(d) Coal is a non-metals and that is why it is not ductile in nature.
