The major component of the water-soluble portion of ash is this element's carbonate, and this metal was the first to be isolated by electrolysis.
The major component of the water-soluble portion of ash is this element's carbonate, and this metal was the first to be isolated by electrolysis. The successful conductance of action potentials relies on the influx of sodium cations and the efflux of the cationic form of this element, which has a higher concentration on the inside of the neuronal soma. Because this cation prevents muscle contractions, its chloride is often used in cardiac surgery to stop the heart. For 10 points, name this chemical element common in bananas, with atomic symbol K.
