How many milliliters of 0.40 m naoh solution are required to titrate 20.0 ml of a 0.30 m h2so4 solution to an end point?

Hello!

The chemical neutralization reaction between NaOH and H₂SO₄ is the following:

2NaOH(aq) + H₂SO₄(aq) → Na₂SO₄(aq) + 2H₂O(l)

So, we can apply the molar equivalence at the endpoint in the following way:



So, 30 mL of NaOH are required to reach an endpoint

Have a nice day!

1) according to the law of conservation of mass ,in all chemical reactions total mass is unchanged
