How do you find the molarity of Khp?
Herein, what is the molarity of Khp?
To determine the molarity of NaOH solution, student took 3.5 g of KHP (KHP – Potassium hydrogen phthalate; Molar mass = 204.22 g/mol) and dissolved in 50 mL of water and titrated with the given unknown molarity NaOH solution loaded in burette.
Furthermore, how do you calculate the molar amount of Khp used to neutralize the NaOH solution? Calculate the molar concentration of the NaOH solution that you prepared Number of moles of KHP = Number of moles NaOH = 2.476 x 10 -3 moles Number of moles NaOH = Mb x Vb Mb = 2.476 x 10 -3 moles / 0.0250 L (equivalence point) = 0.0990 M 3.
In this manner, how do you calculate Khp?
The number of moles of KHP is found by multiplying the moles of NaOH by the mole ratio of KHP to NaOH given by the above, balanced chemical reaction.
How do you find the molarity of standardized NaOH?
- Calculate the number of moles of solute present. mol NaOH. = 15.0g NaOH. x. 1 mol NaOH. 40.0 g NaOH. mol NaOH.
- Calculate the number of liters of solution present. L soln. = 225 mL. x. 1 L. =
- Divide the number of moles of solute by the number of liters of solution. M. = 0.375 mol NaOH. = 1.67 M NaOH. 0.225 L soln.
