Assertion: On addition of sodium bicarbonate to acid, gas bubbles are observed.
Reason: Carbon dioxide is evolved in the reaction.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of the Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.
(c) Assertion is true but Reason is false.
(d) Assertion is false but Reason is true.
Solution:
Both Assertion and Reason are true, and Reason is the correct explanation of the Assertion.
The reaction occurs when sodium bicarbonate reacts with an acid, say HCl, is:
NaHCO3 + HCl → NaCl + H2O + CO2
Carbon dioxide gas show brisk effervescence, i.e. bubbles.
