The ionization equation of sodium dihydrogen phosphate is NaH2PO4=Na++H2PO4-, H2PO4-=H++HPO42-HPO42=H++PO43-. Sodium dihydrogen phosphate has tertiary ionization, also known as acid sodium phosphate, with molecular formulas of NaH2PO4 2H2O and NaH2PO4 and relative molecular weight of156.5438+. The dihydrate is colorless to white crystal or crystalline powder, and the anhydrate is white powder or particles.
Ionization equation is a formula that expresses ionization process with chemical formula and ion symbol. This is a chemical equation, indicating that a substance is dissolved in water or ionized into ions in a molten state. The amount of charge carried by ions can generally be judged according to their valence in compounds. The total positive charge of all cations is equal to the total negative charge of all anions.
Principle: Most of the solvents we come into contact with are water, so the substance that can produce cations in water during ionization is called acid, and the substance that can produce anions in water during ionization is called alkali. If our thinking takes water as the medium to make a breakthrough, the problem will be transferred in a similar way, for example, using liquid ammonia as the solvent.
If the ionization of solute only produces a substance whose cation is hydrogen ion, that is, acid, and ionization only produces a substance whose anion is hydroxide ion, that is, alkali, let's summarize the anions and cations produced by some solvent self-coupling ionization.
