Question

(a) A solution of potassium chloride when mixed with silver nitrate solution an in soluble white substance is formed. write the chemical equation involved and also mention the type of the reaction.
(b) Ferrous sulphate when heated, decomposes with the evolution of a gas having a characteristics colour of burning sulphur. write the chemical reaction involved and identify the type of reaction.​

Answer 1

ans 1

when an aqueous solution of potassium chloride mixed with silver nitrate solution an insoluble white substance is formed I.e.silver chloride

this is double displacement reaction

Answer 2

Answer:

HII MATE

HERE'S THE ANSWER

Explanation:

a.When an aqueous solution of potassium chloride(KCl) when mixed with silver nitrate(AgNO3) solution an insoluble white substance formed is silver chloride(AgCl). The chemical reaction are as follows : KCl(aq) + AgNO3(aq) → KNO3(aq) + AgCl (s). It is an example of double displacement reaction.

b.Ferrous sulphate decomposes with the evolution of a gas having a characteristic odour of burning sulphur. ... Since FeSO4 splits to form three different product, this reaction is a decomposition reaction. This is also a redox reaction since Fe(II) is oxidized to Fe(III) and part of S(VI) is reduced to S(IV).
