Question

Explain the following reaction with balanced equation : (a)precipitationreaction
(b)neutralisation
(c)a reaction that produces effervescence ​

Answer 1

Answer:

Preciputation reaction: Anyvreaction that produces precipitate can be called as precipitation reaction

For eg na2so4(aq) + bacl2(aq) = Baso4(s) +2nacl(aq)

Answer 2

Answer:

(a) The reaction in which an insoluble substance formed, is called a precipitation reaction.

eg. NaCl + AgNO3 = NaNO3 + AgCl(precipitate)

The reaction in which, acids reacts with bases to form sale and water essentially in file aqueous solution are known as neutralization reactions.

eg. HCl + NaOh = NaCl + H2O

(c). Effervescence is the formation of gas bubbles in a liquid by a reaction.
