Anonymous users2024-02-16Acids: The cations produced during dissociation are all hydrogen ion compounds, called acids such as: H2SO4 (sulfuric acid), HCl (hydrochloric acid), HNO3 (nitric acid).
Alkali: The anions produced during dissociation are all hydroxide ion compounds, called alkalis such as: NaOH (sodium hydroxide), KOH (potassium hydroxide), NH4OH (ammonia).
Salts: Compounds that produce metal cations (or NH4) and acid ions during dissociation, called salts such as: Na2CO3 (sodium carbonate), CuSO4 (copper sulfate), NH4NO3 (ammonium nitrate).
The compound formed by the combination of hydrogen ions and acid ions is acid.
The compound formed by the combination of metal ions and acid ions is salt.
The compound formed by the combination of metal ions and hydroxide ions is a base.
Chemical formula of salt: metal beginning + acid end (such as sodium carbonate) Chemical formula of alkali: metal beginning + hydroxide ending (such as sodium hydroxide) Chemical formula of acid: hydrogen element beginning + acid ending (such as hydrochloric acid HCL, nitrate HNO3) Choose me to do it! Thank you!

Anonymous users2024-02-15Acids are generally hydrogen-starting, such as H2SO4 sulfuric acid HCl
Alkalis generally contain hydroxide species, such as naoh koh
Salts are generally composed of metallic elements and acid groups, such as NaCl, Kcl, CaCl2

Anonymous users2024-02-14The method of distinguishing acid-base salts: the compound with all cations H+ is an acid, the compound with an all-oh- anion is a base, and the compound composed of metal ions and acid ions is a salt.
Acids: Acids are also acids in compounds that produce all cations (H+) when ionized, or substances that dissolve in water and release protons to form H3O+ (hydronium ions). Such as hydrochloric acid, sulfuric acid, carbonic acid, nitric acid, etc.
Alkali: The anions ionized in an aqueous solution are all oh- substances, which are bases. Such as lithium hydroxide, sodium hydroxide, rubidium hydroxide, cesium hydroxide, francium hydroxide, etc.
Salts: Compounds in which metal ions or ammonium ions (NH4+) are combined with acid ions or non-metal ions are salts. Such as sodium chloride, calcium nitrate, ferrous sulfate and ammonium acetate, calcium sulfate, copper chloride, sodium acetate, etc.
Mantra about acids and alkalis.
Most acids are soluble, and silicic acid is slightly soluble.
Alkali potassium sodium barium ammonium soluble, calcium is slightly soluble and insoluble.
Lead barium sulfate is immersed in water, slightly soluble calcium, silver and mercury.
The salts are dissolved with potassium, sodium ammonium, plus soluble nitrate.
Carbonic acid can dissolve potassium and sodium ammonium, and the rest is submerged in the middle.
Hydrochloric acid precipitates silver mercurous, as well as slightly soluble lead chloride.
