Step 1

It is given that:

Volume (V1) of solution = 10 mL

Concentration of HCl solution (M1) = 0.25 %

Concentration of available solution of HCl (M2) = 1 %

Step 2

Law of equivalence states that the volume of titrants reacted have same number of equivalents points at the end point of titration. The expression for this is given as follows: help_outlineImage TranscriptioncloseM,V MV where, M,is the concentration of the solution Vis the volume of solution M2is the concentration of new solution V,is the volume of new solution fullscreen
Step 3

Now using law of equivalence equation, the volume o...
