How is potassium carbonate formed?

This salt of carbonate and potassium forms a strongly alkaline solution. K2CO3 is the product of the reaction between liquid potash (KOH) and carbon dioxide. This reaction has two products one is K2CO3 and the other is water, although it has a large capacity to absorb moisture.

What are the side effects of too much potassium?

This chemical compound is used as a safe additive in food and drug organizations in Europe and the United States and also used as a food industry additive, according to the FDA recommendation. The amount is 100 mg per dose, utilization in a high dose causes diarrhea, abdominal pain, pressure, and nausea. The use of foods containing this substance is also not recommended for women during pregnancy and lactation.

This inorganic compound is one of the most widely used materials in today’s industrial society, which we will discuss the most important applications of this material below.

  • As a source of potassium and drying agent in pharmaceutical laboratories.
  • In effervescent tablets and powders to provide potassium in people who suffer from low levels of potassium in the blood.
  • For preparing soap and glass (historically).
  • In animals feed to provide potassium for them.
  • For producing wine or mead as a buffer.
  • Often as a baking agent in some recipes.
  • To soften hard water.
  • Useful for extinguishing fires and preventing the spread of fire. It is more effective in suppressing oil and gas fires than sodium bicarbonate.
  • Ability to produce fertilizer. Due to having K+ ion, it helps the plants to grow and retain water in the soil and strengthens the roots and stems of plants.
