Question

Statement I: According to the equation $M_1{V}_1=M_2{V}_2$, as the volume increases the molarity decreases
Because
Statement II: As water is added to a solution the solution is diluted

• A. one is true ,second is true and currect expilanation of statement 1
• B. one is true second is wrong
• C. True and False
• D. one is False, second is True
• E. False and False

Answer 1

The correct option is A one is true ,second is true and currect expilanation of statement 1

Statement I: According to the equation $M_1{V}_1=M_2{V}_2$
, as the volume increases the molarity decreases
Because
Statement II: As water is added to a solution the solution is diluted
A
True True CE (correct explanation)
Note: With increase in dilution, the number of moles per unit volume decreases and the molarity of the solution is the number of moles of solute per unit volume of solution.
