Question

plzzźzzzz ans. tell, rapidly, instntly ,suddenly, fastly.............​

Answer 1

a) yes precipitate is formed and it is yellow in colour

b) The type of chemical reaction is double displacement.

Double displacement reaction is one in which exchange of ions take place.

In the given reaction barium chromate  does not dissolve and hence remain as solid or a precipitate and potassium sulphate  dissolves.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

Solution of potassium chromate (K2CrO4) reacts with solution of barium sulphate (BaSO4).

a) Yes, in the given reaction a precipitate is formed.

The colour of the precipitate is yellow.

b) The type of the reaction is Double displacement reaction. It is also called Precipitate reaction as in this reaction, a precipitate is formed.

What is meant by chemical reaction?

The reaction in which the composition of the matter changes and that change remains permanent is called Chemical Reaction.

What is meant by Double displacement reaction?

The reaction in which the ions in the reactants are exchanged to form a precipitate is called Double displacement reaction.

Special Feature:-

There is always formation of a precipitate in the double displacement reaction.

What is meant by precipitate?

The precipitate is an insoluble solid which gets separated from the liquid solution.

Examples of Double displacement reaction :-

Barium sulphide reacts with zinc sulphate to form zinc sulphide and a white precipitate of barium sulphate.

Chemical Equation :-

BaS + ZnSO4 ➡️ BaSO4 ⬇️ + ZnS

In this reaction, a precipitate of Barium sulphate (BaSO4) is formed which is shown by an arrow pointing to downwards.
