Potassium hydrogenacetylenedicarboxylate is a potassium salt chemistry salt with chemical formula KC sub 4 sub HO sub 4 sub or K sup sup HC sub 4 sub O sub 4 sub sup &minus sup , often abbreviated as KHadc . It is often called potassium hydrogen acetylenedicarboxylate or monopotassium acetylenedicarboxylate . The salt can be obtained from acetylenedicarboxylic acid and is a common laboratory starting material for the synthesis of other derivatives of that acid. In the crystalline form, the hydrogenacetylenedicarboxylate anions HC sub 4 sub O sub 4 sub sup &minus sup s are joined into linear chains by uncommonly short hydrogen bonds. ref name leban Ivan Leban and Ljubo Goli 1973 , Crystal Structures of the Acid Salts of Some Dibasic Acids.

Potassium is an essential mineral macronutrient ecology macronutrient and is the main intracellular ion ... in the bodies of humans and animals. Potassium ion is necessary for the function of all living cells ... of potassium in plants, associated with comparatively very low amounts of sodium there, historically resulted in potassium first being isolated from the ashes of plants potash , which in turn gave the element its modern name. The high concentration of potassium in plants means that heavy crop production rapidly depletes soils of potassium, and agricultural fertilizers consume 93 of the potassium chemical production of the modern world economy. The functions of potassium and sodium in living organisms are quite different. Animals, in particular, employ sodium and potassium differentially to generate electrical potentials in animal cells, especially in nervous tissue . Potassium depletion ...
