Assertion and Reason type question A) If both assertion and reason are correct and reason is the correct explanation of assertion

B) Both assertion and reason are correct but reason is not the correct explanation of assertion

C) If assertion is correct and reason is not correct

D) Assertion is not correct and reason is correct

Assertion:
⇒ ⇒
⇒ ⇒

Reason:

There are a couple of ways to define acids

and bases

ν Brønsted-Lowry acids and bases

ν Acid: H+ ion donor

ν Base: H+ ion acceptor

ν Lewis acids and bases

ν Acid: electron pair acceptor

ν Base: electron pair donor

ν In most acid-base systems, water may play a

role as either an acid (H+ donor) or a base (H+

acceptor)

Water as an acid

H2O(l) + B(aq) ↔ OH-

(aq) + HB+(aq)

Water as a base

H2O(l) + HA(aq) ↔ H3O+(aq) + A-

(aq)

Explanation:

Acids react with bases and vice versa

ν All acids and bases come with a conjugate

pair—a base or acid, respectively, that is

formed in conjunction with the original

species

Examples

HCl(aq) + H2O(l) ↔ H3O+(aq) + Cl-

(aq)
