SPARKS OF LIFE

Electrolytes are essential minerals that take part in most of the electrochemical processes that sustain life. They share several chemical properties: When dried, they combine into crystalline salts, but when placed into solutions, they dissolve easily into the pure forms. Also, when in solution, the atoms carry a charge, either positive or negative. All are lost in prodigious quantities when a horse sweats and must be replenished. Grass, hay and grains contain ample amounts of most electrolytes---with two exceptions that must come from another source. Which two electrolytes are these feeds missing? a. phosphate and calcium b. sodium and chloride c. bicarbonate and magnesium d. potassium and calcium
