STATEMENT-1: Solubility of AgCN in acidic solution is greater than that in pure water. STATEMENT-2: Solubility equilibrin of AgCN in acidic solution is shifted in forward direction due to formation of HNC.
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
Assertion (A): Solubility of AgCN in acidic solutions is greater than in pure water. Reason (R) : Solubility equilibrium of AgCN is shifted in formwed direction due to the formation of HCN .
STATEMENT-1: Solubility of sparingly soluble salt decreases due to common ion effect. STATEMENT-2: Solubility product constant does not depend on common ion effect.
STATEMENT-1: Solubility product of BaF_(2) will increase on dilution. STATEMENT-2: Solubility of BaF_(2) will change on changing temperature.
STATEMENT-1: All strong monoprotic acid with same concentration in dilute solution show same pH. STATEMENT-2: Water shows levelling effect.
each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: Colloidal solution is electrically neutral. STATEMENT-2: Due to similar nature of the charge carried by the dispersed phase particles, they repel each other and do not combine to form bigger particles.
Lower carboxylic acids are soluble in water due to
STATEMENT-1: Sparingly soluble salts AB and XY_(2) with the same solubility product, will have different solubility. STATEMENT-2: Solubiluty of sparingly soluble salt depend upon solubility product.
Choose the correct set of True/Fasle for following statements: (i) Silver chloride is more soluble in very concentrated sodium chloride solution than in pure water. (ii) The pH of a buffer solution does not change on addition of small amount of an acid or a base. (iii) Addition of NH_(4)Cl does not affect the pH of a solution of NH_(4)OH (iv) Degree of hydrolysis of ammonium acetate does not depend upon the concentration of ammonium acetate solution. (v) A mixture of acetic acid and sodium acetate can act as buffer solution.
