Explanation / Answer

Answer:

1.

Given:

End point = 15.34 ml

Molarity of NaOH=0.1 M

Total volume of KHP + water = 1 + 20 = 21 ml

find Concentration of KHP=?

First to find the moles of NaOH

Molarity= Moles/Volume in lit.

Moles= Molarity X volume in lit

moles = 0.1 M X 0.01534 L =0.001534 mole/lit

KHC8H4O4 + NaOH --------> NaKC8H4O4 + H2O

The number of moles of acid can be related to the number of moles of base using the balanced equation.

Moles of acid=moles of base =0.001534 mole/lit

you have to find the concentra of KHP=?

Molarity of KHP = Moles of KHP / Volume in lit.

Molarity of KHP =0.001534 mole/lit /0.021 L

Molarity of KHP=0.0730 M -------Answer
