Potassium carbonate
Potassium carbonate, K2CO3, appears as a white powder or as colorless solid crystal and has a salty taste. Also known as potash or pearl ash, it may be used in pharmaceutical laboratories as a drying agent or as a source of potassium. It also used in fire extinguishers, to make soap, to make glass, and to soften water.[1] It is also found in effervescent tablets. Effervescent tablets and powders are available to provide potassium when there are low levels of potassium in the blood due to inadequate diet, nausea and vomiting, diarrhea or use of certain medications such as corticosteroids or diuretics
