The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as khp). khp is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. in the titration, 24.46 ml of the sodium hydroxide solution was required to react with 0.1082 g khp. calculate the molarity of the sodium hydroxide.

Explanation:

Moles of KHP :

Given, Mass of KHP = 0.1082 g

Molar mass of KHP = 204.22 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the reaction shown below:

KHP + NaOH ⇒ KNaP + H₂O

1 mole of KHP reacts with 1 mole of NaOH

So,

of KHP reacts with of NaOH

Moles of NaOH =

Volume = 24.46 mL = 0.02446 L ( 1 mL = 0.001 L)

what does the table look like

56 moles of   lieter in chemistry
