(Choose the correct answer from the option given below)
Que-1: The colour of an aqueous solution of copper sulphate is:
(a) Green
(b) Brown
(c) Blue
(d) Yellow
Ans: (c) Blue
Hint: Aqueous solution of copper sulphate is blue.
Que-2: The colour of the precipitate formed on adding NaOH solution to iron (II) sulphate solution is:
(a) White
(b) Brown
(c) Green
(d) Pale blue
Ans: (c) Green
Hint: Dirty green precipitate of Ferrous Hydroxide [Fe(OH)2] is formed.
Que-3: A metal which produces hydrogen on reacting with alkali as well as with acid:
(a) Iron
(b) Magnesium
(c) Zinc
(d) Copper
Ans: (c) Zinc
Hint: Reactions of Zinc with alkali and acid are shown below:
Zn + 2NaOH ⟶ Na2(ZnO)2 + H2↑
Zn + HCl ⟶ ZnCl2 + H2↑
Que-4: The salt solution which does not react with ammonium hydroxide is:
(a) Calcium nitrate
(b) Zinc nitrate
(c) Lead nitrate
(d) Copper nitrate
Ans: (a) Calcium Nitrate
Hint: No ppt. occurs even with addition of excess of ammonium hydroxide as the concentration of OH- ions from the ionization of of NH4OH is so low that it cannot precipitate the hydroxide of calcium.
Que-5: Which of the following is the best reagent to distinguish lead nitrate and zinc nitrate ?
P NaOH solution
Q KOH solution
R NH4OH solution
(a) Only P
(b) Only R
(c) Only Q
(d) Both P and Q
Ans: (a) Both P and Q
The following questions are Assertion-Reason based questions. Choose the answer based on the codes given below.
1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
Que-6:
Assertion (A): Calcium salt solution does not show any change even after adding an excess of ammonia solution to it.
Reason (R): The low concentration of hydroxide ion in ammonium hydroxide solution which are unable to precipitate the hydroxide ions of calcium
(a) (1)
(b) (2)
(c) (3)
(d) (4)
Ans: (a) (1)Both A and R are true and R is the correct explanation of A.
Hint: Calcium salt will not show precipitation even with addition of excess of NH4OH. This is because the concentration of OH- ions from the ionization of NH4OH is so low that it cannot precipitate the hydroxide of calcium. Hence both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Que-7:
Assertion (A): Iron (II) salt solution when reacted with ammonium hydroxide forms a dirty green precipitate.
Reason (R): Iron salts are brown in colour.
(a) (1)
(b) (2)
(c) (3)
(d) (4)
Ans: (c) (3)A is true but R is false.
Que-8:
Assertion (A): Hydrogen gas is liberated when metals like Zn, Al, Pb react with caustic alkalies.
Reason (R): Alkalies are soluble in water.
(a) (1)
(b) (2)
(c) (3)
(d) (4)
Ans: (b) (2)Both A and R are true but R is not the correct explanation of A.
Que-9:
Assertion (A): Oxides of most of the metals are basic in nature.
Reason (R): All metal oxides dissolve in water forming alkalis.
(a) (1)
(b) (2)
(c) (3)
(d) (4)
Ans: (c) (3)A is true but R is false.
Que-10:
Assertion (A): Zinc oxide reacts with acids as well as bases to form salt and water.
Reason (R): Zinc oxide is amphoteric in nature.
(a) (1)
(b) (2)
(c) (3)
(d) (4)
Ans: (a) (1)Both A and R are true and R is the correct explanation of A.
