Question

State as to why sodium is found to be more useful than potassium?

Answer 1

Blood plasma and the interstitial fluids surrounding the cells are the regions where sodium ions are primarily found. Potassium ions are located within the cell fluids. Sodium ions are involved in the transmission of nerve signals, in regulating the flow of water across the cell membranes, and in transporting sugars and amino acids into the cells. Hence, sodium is found to be more useful than potassium.

Answer 2

Since potassium is move reactive than sodium and it is found in nature to a less extent than Na, sodium is found to be more useful.
