Question

on dipping blue Litmus Paper in solution A it remain as it is while solution B turn blue Litmus Paper to Red when A and B solution are mixed and blue Litmus Paper dipped in it its colour remains unchanged
1. Predict the nature of A and B
2 name the reaction taking place between Aand B
2. Write chemical equation by giving an example of such a reaction​

Answer 1

B is acid

A is base

base + acid ------> neutral

reaction is neutralisation reaction

acid + base ---->salt + water

example

HCl+NaOH------>NaCl(salt)(neutral)+H20

Answer 2

1. A_ is basic in nature whereas.

B_is acidic in nature .

2. when acid and base reacts with each other it forms salt and water which is known as neutralisation reaction.

for eg., NaOH + HCL → NaCl + H2O
