What are the importance of sodium bicarbonic and sodium chloride?

Answer 1

Sodium chloride NaCl is one of the most common salts. It is the salt in the Oceans. It is the primary source of Sodium (which is necessary for many biologic functions) for most living creatures.

I have never heard of sodium bicarbonic but sodium bicarbonate or sodium hydrogen carbonate is the chemical compound with the formula NaHCO3. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.

Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. In colloquial usage, its name is shortened to sodium bicarb, bicarb soda, or simply bicarb.
