Where to find Potassium Sulphate<\/h2>\n

Natural sources:<\/strong> Natural sources of potassium sulphate are those salts which contain large amounts of magnesium. The minerals are: Kainite, Sch\u00f6nite, Leonite, Langbeinite, Glaserite, Polyhalite.<\/p>\n

Synthesis:<\/strong> It is very common to obtain it through synthesis in industry. It can be synthesised through the reaction of sulphuric acid with potassium hydroxide, the formula being as follows: H2<\/sub>SO4<\/sub> + 2KOH -> K2<\/sub>SO4<\/sub> + 2H2<\/sub>O.<\/p>\n
