Calcium chloride - definition of calcium chloride by …

Calcium chloride has been acknowledged as being more advantaged than sodium chloride since calcium chloride solutes in water and emits heat (an exothermic process takes place), in the result of which the adjacent materials are heated in a contact with soluting sodium chloride.

Biological Importance of Magnesium and Calcium - …

Low magnesium intake will increase more storage of calcium in the body. Ialance in magnesium allows too much calcium to be stored in the body. Role of Magnesium in Calcium Absorption. Magnesium is essential for calcium absorption. Without magnesium, calcium may get deposited in soft tissues and can cause arthritis.
