Questions And Answer

Description
Potassium acetate is the potassium salt of acetic acid. It is manufactured through the reaction between a potassium base such as potassium hydroxide or potassium carbonate with acetic acid. It is an important macromineral with many physiological functions and is required for nerve conduction, cardiac, skeletal and smooth muscle contraction, energy generation, nucleic acid synthesis as well as mainlining the blood pressure and normal renal function. It can be taken as a nutritional supplement with antihypertensive effects and prevention effects against hypokalemia. It has several other common applications: (1) as a deicer; (2) as a food additive; (3) molecular biology applications such as DNA purification, tissue preservation, fixation and mummification; (4) Death penalty (5) as the catalyst during the production of polyurethanes.

Questions and Answers (Q&A)

Uses
Potassium acetate is used in the manufacture of glass; as a softening agent for papers and textiles; as a dehydrating agent; and as a buffer. In medicine it is used as an expectorant and diuretic.
Preparation
Potassium acetate is prepared by addition of potassium carbonate in a small volume of water to acetic acid solution, followed by evaporation and crystallization:
K2CO3+ 2CH3COOH →2CH3COOK + H2O
