Neutralization
Neutralization

Neutralization, is a chemical ,reaction,, also called a water forming ,reaction,, in which an ,acid, and a base or ,alkali, (soluble base) react and produce a salt and water(H 2 O). In other words, it can be said that ,neutralization, is the combination of hydrogen ions H + and hydroxide ions OH − (or oxide ions O 2−) to form water molecule H 2 O. In the process, a salt is formed.

Industrial synthesis of oxalic acid - reactionchamber

The reaction works best with a catalyst such as vanadium pentoxide or iron. The nitric oxide is used to regenerate nitric acid. Another method for the production of oxalic acid started from cellulose. To this end, sawdust was subjected to an oxidizing alkali melt. This procedure gave only low yields also, the amount of wastewater was very high.
