assertion true solution exhibits Tyndall effect reason particals of true solution are very small in size. part (a). if both assertion and reason are correct and reason is correct explanation of assertion. part ((b). if both assertion and reason are correct but reason is not the correct explanation of assertion. part(c).if assertion is correct but reason is incorrect. (d). if assertion is incorrect but reason is correct.
Answers
Answer:
(d) Assertion is false, but reason is true.
Explanation:
True solution do not exhibit Tyndall effect, since the particle size is very small.
From the given question the correct answer is:
(d). if assertion is incorrect but reason is correct.
Assertion : true solution exhibits Tyndall effect
Reason: particals of true solution are very small in size. part
(d). if assertion is incorrect but reason is correct.
The explanation of Assertion
The phenomenon by which colloidal particles scatter light is called Tyndall effect. The particles of colloids scatter a beam of light passing through it and make its path visible. True solutions do not show Tyndall effect.
The explanation of reason
a true solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the particle size of less than 1 nm or 0.001 micrometers
