Assertion : When a connection solution is diluted by acidic aqueous solution remains unchanged . Reason: Product of moles of aolute and volume is equal to the molarity.

Answer»

if both assertion and REASON are true and reason is thr CORRECT EXPLANATIONOF assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reson are false.

Solution :Molarity equation is WRITTEN as
`M_1 v_1 =M_2 V_2 ` thus if the d`V_2 ` changes `M_2 ` also changes .
`"Molarity " =("moles of solute ")/(" volume of solution in litre ")`
