Calcium nitrate - Revolvy

Calcium nitrate , also called Norgessalpeter (Norwegian saltpeter), is the inorganic compound with the formula Ca(NO). This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate . It is mainly used as a component in fertilizers but has other appliions. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence

What is the reaction between magnesium oxide and

Magnesium oxide reacts with hydrochloric acid to form magnesium chloride salt and water. In neutralisation process, an acid reacts with an alkali to form salt and water. So in this case the acid is hydrochloric acid and magnesium oxide is the alkali. As we know, hydrochloric acid is made up of hydrogen ion (ion) and chloride ion (anion).
