WebThe reference standard KHP (for Potassium Hydrogen Phthalate) has a formula weight of 204.22 g/mol. KHP is a weak monoprotic acid which reacts 1: 1 with NaOH. You dissolve 0.2877 g of KHP in 40.0 mL of de-ionized water and titrate with a NaOH solution (titrant) to reach the equivalence point-this requires 24.71mLs of titrant. http://chem.tamu.edu/class/fyp/mcquest/ch11.html
WebMar 28, 2024 · Molecular weight of KHP = 20.42 g. From the reaction, 1 mol of NaOH is equivalent to 1 mol of KHP. Hence, 1000 ml of 1 M NaOH is equivalent to 20.42 g of KHP. So, 1 ml of 1 M NaOH is equivalent to 0.2042 g of KHP. (B) Determination of Normality: 1 ml of 1 M NaOH is equivalent to 0.2042 g of KHP.

WebNov 1, 2024 · Name: Potassium Hydrogen Phthalate Alias: KHP Formula: KHC8H4O4 Molar Mass: 204.2212 KHC8H4O4 is a white solid at room temperature. It is soluble in water. Its melting point is 295 ̊C (563 ̊F), density 1.636 g/cm3. KHC8H4O4 can be used for pH meter calibration or as a buffer agent. WebThe pKa of KHP is 5.4, so its pH buffering range would be 4.4 to 6.4; however, due to the presence of the second acidic group that bears the potassium ion, the first pKa also contributes to the buffering range well below pH 4.0, which is why KHP is a good choice …
