What is the molar mass of KHP?
204.22 g/molPotassium hydrogen phthalate / Molar mass
KHP (MWT = 204.22 g/mol) is a monobasic acid that contains one mole of neutralizable hydrogen per mole of compound.
How do you calculate mol of KHP?
The number of moles of KHP is found by dividing the mass of KHP by the molecular weight of KHP. 2.
How do you make 0.1 m in KHP?
You will need to make 250 mL of approximately 0.1 M KHP. Clean a 250 mL volumetric flask, and rinse it several times with deionized water. Make sure to wet the inner walls of the flask completely each time. Note: all masses must be measured to ± 0.001 g or ± 0.0001 g.
What is the Ka value of KHP?
Because the concentration of water is presumed constant and therefore not included in the expression, the equilibrium constant for this reaction is called acid dissociation constant, Ka . Ka=3.9⋅10−6 , which confirms that KHP is a weak acid.
How do you calculate KHP formula weight?
204.22 g/molPotassium hydrogen phthalate / Molar mass
Is KHP a primary standard?
Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity; is relatively inexpensive; is easy to dry; is neither hygroscopic, oxidized by air, nor affected by Carbon Dioxide (thus making it easy to weigh out); does not undergo decomposition during storage; …
How do you find moles from molar mass and ML?
MOLES FROM VOLUME OF PURE LIQUID OR SOLID There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.
How do you calculate normality of KHP?
Calculate the normality of the NaOH using the titration volume 49.1 mL of NaOH , the 2.16 g KHP used, and the equivalent mass of KHP, making the assumption that potassium acid phthalate is 100.00% pure. Normality = [(grams KHP)/(0.20423 g/meq KHP)]/(mL NaOH)
How is the standard 0.05 m KHP solution prepared?
Answer: Preparation of Standard KHP Solution Clean a 250 mL volumetric flask, and rinse it several times with deionized water. Make sure to wet the inner walls of the flask completely each time. Note: all masses must be measured to ± 0.001 g or ± 0.0001 g.
