How do you find the molar mass of KHP?
KHP (MWT = 204.22 g/mol) is a monobasic acid that contains one mole of neutralizable hydrogen per mole of compound.
How many moles of KHP react with NaOH?
one mole
In this reaction as well, one mole of KHP completely reacts with one mole of NaOH. The titration of NaOH with KHP involves adding NaOH from the burette to a known volume of KHP. The molarity of the KHP solution is determined from the mass and volume of KHP used to prepare the KHP solution.

What is the molarity of NaOH when titrated with KHP?
Molarity of NaOH = (mol KHP)/ (V NaOH used for titration): M(NaOH)=0,00213mol0,03103L=0,0688molL .
What is the reaction between KHP and NaOH?
reaction is called a neutralization reaction because two caustic compounds, KHP, a mild acid, and NaOH, a strong base, are replaced by water and a weaker base.
Is potassium hydrogen phthalate 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; …

What is the pKa of KHP in KHP?
KHP can be used as a buffering agent in combination with hydrochloric acid (HCl) or sodium hydroxide (NaOH). The buffering region is dependent upon the pKa, and is typically +/- 1.0 pH units of the pKa. The pKa of KHP is 5.4, so it’s pH buffering range is 4.4 to 6.4. KHP is also a useful standard for total organic carbon (TOC) testing.
Is KHP an acid or base or neutral?
Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable,
