A32.00 ml sample of an unknown h3po4 solution is titrated with a 0.110 m naoh solution. the equivalence point is reached when 24.83 ml of naoh solution is added. what is the concentration of the unknown h3po4 solution? the neutralization reaction is
h3po4(aq)+3naoh(aq)→3h2o(l)+na3po4( aq)

Concentration of in sample is 0.25 M.

Explanation:

From the reaction, one mole of reacts with 3 moles of NaOH.

Now, number of moles of NaOH, n =

Therefore, mol of NaOH reacts with .

So, concentration of

Therefore, concentration of in sample is 0.25 M.

Hence, this is the required solution.
