An impure sample of potassium hydrogen phthalate (KHP) was titrated to determine the percent composition KHP. What is the percent of KHP if 2.81 g of the impure KHP required 35.61 mL of 0.152 M NaOH to reach the end point?

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
