How many milliliters of 0.250 M KoH will be needed to titrate 12.53 mL of 0.130 M #HNO_3#?
You will need 6.516 mL of KOH to reach the equivalence point.
Since KOH has only one
And since moles (of solute) = concentration x volume, we can write
We know the first three quantities in this equation. We find the fourth (
We need (i) a stoichiometric equation........
And then (ii) equivalent quantities of potassium hydroxide and nitric acid:
And thus we need
