Tresset [83]

A 25.00 ml sample of hydrochloric acid solution, HCl, is titrated with 0.0512 m NaOH solution. the volume of NaOH solution required is 21.68 ml  then the molarity of the HCl solution is 0.044 M .

Calculation ,

Formula used : M_{1} V_{1} =M_{2} V_{2}                            ...( i )

Where M is the molarity or concentration and V is the volume in ml .

concentration of hydrochloric acid solution ( M_{1}    ) = ?

concentration of NaOH ( M_{2} ) = 0.0512 M

volume of hydrochloric acid solution  ( V_{1} ) = 25.00 ml

volume of NaOH ( V_{2} ) =  21.68 ml

Putting the value of concentration , volume of both  in equation ( i ) we get .

M_{1}   × 25.00 ml = 0.0512 × 21.68 ml

M_{1}    = 0.0512 × 21.68 ml / 25.00 ml= 0.044 M
