Assertion (A) : ROH does not react with NaBr.
Reaction (R ) : `Br^(-)` is an extremely weak Bronsted base and cannot displace strong base `OH^(-)` .

Assertion : Alcohols cannot be converted into alkyl bromides by reaction with NaBr Reason : Br^(-) being very weak base cannot displace strong base OH^(-)

Assertion (A ) : Acetic acid is a weak acid Reason (R ) : Its conjugate base is weak

Assertion (A) : Sodium hydrogen carbonate is an acidic salt. Reason (R) : It is a salt produced by the neutralization reaction between a strong base (NaOH) and a weak acid (H_(2)CO_(3)) .

Assertion (A): BaCO_(3) is more soluble in HNO_(3) than in water. Reason (R ): Carbonate is a weak base and reacts with H^(o+) ions to form strong acid causing barium salt to dissociate.

Assertion (A): BaCO_(3) is more soluble in HNO_(3) than in water. Reason (R ): Carbonate is a weak base and reacts with H^(o+) ions to form strong acid causing barium salt to dissociate.

Assertion : CaO +SO_3 to CaSO_3 in an acid base reaction Reason: It is in accordance with Bronsted concept.

Assertion: Alcohols give only substitution products with HX and not elimination product. Reason: X^(-) is a very weak base which cannot abstract proton from alcohol.

Assertion : Ionic hydrides like hydrolith liberates hydrogen gas on reaction with water. Reason : The resultant soution acts as strong base.

Assertion (A) : Aqueous solutions of ZnSO_4 is neutral. Reason ( R ) : Salt of strong base and weak acid undergoes anionic hydrolysis.
