Potassium sulphate (UK) or potassium sulfate (US) is an inorganic chemical link which is also known as sulfate of potash, arcanite or was previously additionally known as potash the sulfur. It is an ionic link which when dissolved in water dissociates right into two ion - potassium cation and also sulphate anion. By definition, a sulfate or sulphate ion is a polyatomic anion v an overall electrical fee of -2. ~ above the various other hand, Potassium can lose just one electron because that attaining steady valence electronic configuration. Hence, from this facts, you can conveniently determine the the neutral potassium sulfate formula will have two cations that potassium and also one anion the sulphate. Hence, the chemical formula the potassium sulphate is offered as K2SO4. Thus, K2SO4 is the answer come be given when inquiry what is the chemistry formula of potassium sulphate or what is the potassium sulphate chemistry formula.

General properties of Potassium Sulphate
Potassium sulphate is a white and odourless solid and also is more commonly well-known for its helpful properties as a fertilizer. That serves together a great source that potassium and also sulfur because that the plants together is depicted by the formula for potassium sulphate.
From the potassium sulphate formula or the potassium sulfate formula (whichever you room comfortable with), that is basic to calculate one of the physics properties the the link - the molar mass. The molar mass of potassium sulphate as figured out by the potassium sulphate formula is 174.26 /mol. Few of the other physical properties the cannot be derived from potassium sulfate formula are detailed below:
The thickness of the compound is 2.7 g/cm3.
The boiling point and the melting point of potassium sulphate room high. They room 1689℃ and 1069℃ respectively.
The ionic link is extremely soluble in water, sparingly soluble in glycerol solution and also insoluble in solutions made up of acetone, alcohol, and also cesium sulphide.
It is a non-flammable not natural compound.

The crystals of potassium sulphate room transparent, really hard and are bitter and salty in taste.
Structural Characterisation of Potassium Sulphate
The structural formula the potassium sulphate shows the two potassium ions about the sulphate ions as shown by the molecular formula the potassium sulphate. It is stood for as follows:
Potassium sulphate is naturally accessible in the mineral type of arcanite. That is a relatively rare mineral and also hence an ext potassium sulphate have the right to be uncovered in the cocrystallization the potassium sulphate through magnesium sulphate, calcium sulphate or sodium sulphate. The crystal framework of the potassium sulphate mineral is orthorhombic. It exists in 2 crystalline creates -
