Question

Assertion: Lime water becomes turbid on passing $C{O}_2$ but becomes clear on passing more $C{O}_2$
Reason : Lime water is calcium hydroxide, $Ca(OH{)}_2$

• A. If both assertion and reason are true and the reason is a correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not a correct explanation of the assertion.
• C. If the assertion is true but reason is false.
• D. If both the assertion and reason are false.
• E. If the assertion is false but the reason is true

Answer 1

The correct option is B If both assertion and reason are true but reason is not a correct explanation of the assertion.

${CO}_2+Ca{\left(OH\right)}_2⟶\underset{Insoluble}{Ca{CO}_3}\downarrow +H_{2}O$
$Ca{CO}_3+{CO}_2+H_{2}O⟶\underset{soluble}{Ca{\left(H{CO}_3\right)}_2}$
