What volume of 01151 M NaOH is needed to titrate 125100 m L

What volume of 0.1151 M NaOH is needed to titrate 12.5100 m L of 0.2130 M acetic acid to the phenolphthalein endpoint?

Solution

V₁N₁=V₂N₂

You can use the above formula for finding answer.

V₁= Volume of NaOH , N₁= Strength of NaOH

V₂= Volume of Acitc acid N₂= Strength of acitic acid

0.1151 x V₁= 12.5100 x 0.2130

you need 23.1505 mL NaOH.
