Molar mass: 204.222 g·mol −1 Appearance White or colorless solid ... Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound.
Molar mass: 166.132 g/mol Appearance white solid Density: ... The monopotassium salt, potassium hydrogen phthalate is a standard acid in analytical chemistry.
It is necessary to calculate the mass of a solid acid which will react with about 20 cm 3 of this solution (for a titration using a 25 cm 3 burette): suitable solid acids include oxalic acid dihydrate, potassium hydrogen phthalate and potassium hydrogen iodate. The equivalent weights of the three acids 63.04 g, 204.23 g and 389.92 g ...
Where W KHP is the mass (g) of potassium hydrogen phthalate (KHP) in 50 ml of KHP standard solution, V eq is the volume of titrant (ml) consumed by 50 ml KHP standard solution at the equivalent point,
This includes Bis(2-ethylhexyl) phthalate (DEHP or DOP), which has long been the most widely used phthalate, with commercial production dating back to the 1930s. [ 16 ] [ 17 ] In the EU, the use of DEHP is restricted under REACH and it can only be used in specific cases if an authorisation has been granted; similar restrictions exist in many ...
Dipotassium phosphate (K 2 HPO 4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K 2 HPO 4. (H 2 O) x (x = 0, 3, 6). Together with monopotassium phosphate (KH 2 PO 4. (H 2 O) x), it is often used as a fertilizer, food additive, and buffering agent. [1]
Potassium bromate (KBrO 3) for standardisation of sodium thiosulfate solutions; Potassium hydrogen phthalate (usually called KHP) for standardisation of aqueous base and perchloric acid in acetic acid solutions; Sodium carbonate for standardisation of aqueous acids: hydrochloric, sulfuric acid and nitric acid solutions (but not acetic acid)
