Assertion (A): Solubility of `AgCN` in acidic solutions is greater than in pure water. Reason (R) : Solubility equilibrium of `AgCN` is shifted in forward direction due to the formation of `HCN`.
A
If both the statements are TRUE and STATEMENT-2 is the correct explation of STATEMENT-1
B
If both the statements are TRUE AND STATEMENT-2 is NOT the correct explanation of STATEMENT-1
The solublity of I_2 in KI solution is more than its solubility in pure water because
AgCl is less soluble in AgNO_(3) solution than in pure water. Explain.
Assertion (A): NaCl is less soluble in heavy water than in ordinary water. Reason (R): Dielectric constant of ordinary water is more than that of heavy water.
Assertion: The vapour pressure of mixture of ethanol and water is greater than pure water. Reason: Ethanol & water form an azeotropic mixture.
(A) : The solubility of maleic acid in water is higher than that of fumaric acid . (R) : Maleic acid and fumaric acids are cistrans isomers.
Assertion:The molecular mass of acetic acid in benzene is more than the actual value of the solute. Reason: Molecules of acetic acid dimerise in benzene due to hydrogen bonding.
Assertion (A) : P^(H) of an aqueous solution of acetic acid remians unchanged on the addition of sodium acetate. Reason ( R ) : Dissociation of acetic acid is supressed by the addition of soidum acetate due to common ion effect.
Assertion : A very dilute acidic solution of Cd^(2+) and Ni^(2+) gives yellow ppt. of CdS on passing H_(2)S . Statement: Solubility product of CdS is more than that of NiS.
