Assertion (A): Carbon dioxide turns lime water milky.
Reason (R): Carbon dioxide sullies the water.
Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true but reason (R) is false.
(d) Assertion (A) is false but reason (R) is true.
To sully means to damage the purity.
Here, the reaction is
Carbon dioxide does not damage the purity of lime water. It just reacts with lime water (calcium hydroxide) to form milky precipitate of calcium carbonate.
- Assertion is true
- Reasoning is false
So, the correct answer is (c)
