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`.
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
"A" is a soluble acidic oxide. compared to pH of pure water what will be the pH of solution A ?
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.
The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: The number of electrons in a p-type silicon semiconductor is less than the number of electrons in pure silicon semiconductor at room temperature. Reason: It is due to law os mass action.
These question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following responses If both Assertion and Reason are true and Reason is a correct explanation of Assertion If both Assertion and Reason is a not a correct explanation of Assertion If Assertion is true but Reason is false If both Assertion and Reason are false Assertion: BaCO_3 is more soluble in HNO_3 than in plain water. Reason: Carbonate is a weak base and reacts with the H^+ from the strong acid, causing the barium salt to dissociate.
Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : All solute becomes more soluble in water at higher temperature. STATEMENT - 2 : Solubility of solute depends upon tempreature.
Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason). Examine the statements carefully and mark the correct answer according to the instruction given below: STATEMENT-1:For a chemical reaction at initial stage rate of forward reaction ( r_(f) ) is greater than rate of reversed reaction( r_(b) ) STATEMENT-2: When r_(f)=r_(b) ,chemical reaction is at equilibrium.
