Question

During performing an experiment on neutralisation reaction, Ravi took

about 100 mL of sodium hydroxide solution and pour approximately the same

amount of concentrated hydrochloric acid to it.

He observed a very vigorous reaction with evolution of large amount of heat.

When he dipped litmus paper into the solution it turned red. He was surprised

with the result though he had read all the instructions and precautions given to

him by his teacher.

(a) What was the expected result of the experiment?

(b) What went wrong in the experiment performed by Ravi?

(c) Why Ravi observed a very vigorous reaction with evolution of large amount

of heat when he added concentrated hydrochloric acid to sodium hydroxid​

Answer 1

a) As it was a nutralisation reaction, so water and salt must be formed .

b)He should have added the base of in same concentration.

c) Because he added concentrated hydrochloric acid.
