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 phosphate is a generic term for the salts of potassium and phosphate ions including: [1] Monopotassium phosphate (KH 2 PO 4) (Molar mass approx: 136 g/mol) Dipotassium phosphate (K 2 HPO 4) (Molar mass approx: 174 g/mol) Tripotassium phosphate (K 3 PO 4) (Molar mass approx: 212.27 g/mol) As food additives, potassium phosphates have ...

Monopotassium phosphate (MKP) (also, potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH 2 PO 4. Together with dipotassium phosphate (K 2 HPO 4. (H 2 O) x) it is often used as a fertilizer, food additive, and buffering agent.
Tripotassium phosphate, also called tribasic potassium phosphate [3] is a water-soluble salt with the chemical formula K 3 PO 4. (H 2 O) x (x = 0, 3, 7, 9). [ 4 ] Tripotassium phosphate is basic: a 1% aqueous solution has a pH of 11.8.
It is manufactured by treating an aqueous solution of potassium carbonate or potassium hydroxide with carbon dioxide: [1] K 2 CO 3 + CO 2 + H 2 O → 2 KHCO 3. Decomposition of the bicarbonate occurs between 100 and 120 °C (212 and 248 °F): 2 KHCO 3 → K 2 CO 3 + CO 2 + H 2 O. This reaction is employed to prepare high purity potassium carbonate.
where is the chemical potential of the pure solvent and is the chemical potential of the solvent in a solution, M A is its molar mass, x A its mole fraction, R the gas constant and T the temperature in Kelvin. [1] The latter osmotic coefficient is sometimes called the rational osmotic coefficient. The values for the two definitions are ...
In chemistry, acid value (AV, acid number, neutralization number or acidity) is a number used to quantify the acidity of a given chemical substance.It is the quantity of base (usually potassium hydroxide (KOH)), expressed as milligrams of KOH required to neutralize the acidic constituents in 1 gram of a sample.
