During electrolysis calcium is also obtained at hode but sodium and calcium are separated from each other due difference in density. Density of Na is 0.67gm/cc and the density of Ca is much higher than that of Na i.e. 2.54gm/cc.
Chemical Properties of Metals and Non Metals @ BYJU''S
Reaction Of Metal With Oxygen Metals react with oxygen to form metal oxides. Metals donate electrons to oxygen for the formation of metal oxides. For example, 4K + O 2 → 2 K 2 O Metal oxides are generally basic in nature but it can also be amphoteric in
Water Hardness S''05 - Pennsylvania State University
A metal ion indior is a compound whose color changes when it binds to a metal ion. For such an indior to be useful in the titration of a metal with EDTA, the indior must give up its metal ion to the EDTA. The indior in its free form, i.e. not bound to any

A chemical equation shows the reactants and products of a chemical reaction. When NaCl is placed in water, it dissolves--physical process. No chemical reaction takes place. As
The Role of Calcium in the Human Body
When calcium levels in the body fall too low, the bones have to supply calcium to tissues and fluids so that normal biological functions can continue. As a result, calcium deficiency can cause the bones to weaken, raising the risk of fracture and increasing the risk of osteoporosis.
Reaction of Aluminum with Water to Produce Hydrogen
Introduction: The concept of producing hydrogen by the reaction of certain metals with water was first proposed in the late nineteenth century (1). In more recent times, a paper by Smith in 1972 described an approach using an amalgamated aluminum surface (2).
