Explanation / Answer

You have 100 ml of 1 M HCl and you want to titrate this using 1 M of NaOH

the reaction is HCl+NaOH ==== NaCl + H2O

as you can see you need 1 mole of HCl to neutralize 1 mole of NaOH

since both solutions are 1 M then we need the same amount of militers to reach equivalence point so

1 ml of HCl will neutralize 1 ml of NaOH

so equivalence point

100 ml of HCl require 100 ml of NaOH

Equivalence point 100 ml of 1 M NaOH

Everything that has a volume lower than 100 is considered to be "before equivalence point"

50 ml of 1 M naoh

5 ml of 1 M naoh

10 ml of 1 M naoh

Everything that has a volume higher than 100 ml is considered to be "after the equivalence point" (At this point all the HCl is gone, you have NaOH in the flask)

150 ml of 1 M naoh

200 ml of 1 M naoh

Remember that equivalence point can only be 1

When you havent neutralized all the acid you will be at the "before equivalent point" region

When have neutralized all the acid and you have NaOH unreacted you will be at the "after equivalence point" region
