K3po4 is a white, odorless and deliquescent salt that contains both potassium and phosphorus. It is used in various applications including fertilizers and food additives. It has an orthorhombic crystal structure and consists of PO4 tetrahedra sharing oxygen atoms with each other. This compound can be synthesized by reacting phosphoric acid with potassium hydroxide (KOH) or thermally decomposing it from potassium carbonate. It is also found in nature as part of certain biochemical pathways and is produced from mineral ores.
Potassium phosphate is soluble in hot water and cold water and is slightly soluble in ethanol. It is a moderately toxic compound that can cause skin, eye and respiratory irritation in high concentrations. It can also be dangerous if mixed with incompatible chemicals such as acids and oxidizing agents.
Boiling point elevation is the increase in the boiling temperature of a solution due to the addition of a solute. It can be estimated by multiplying the molality of a solution with the ebullioscopic constant (or boiling point elevation constant), which is determined from a van’t Hoff factor and the molar concentration of the solute in the solvent.
This calculator allows you to estimate the boiling point elevation of a solution with 3.39m K3PO4 given that it ionizes completely. It takes into account the molar concentration of the solute and the van’t Hoff factor, which is equal to 4 since each K3PO4 ion dissociates into 3 K+ and 1 PO4
