Which one is more acidic, silicate or carbonate?

Silicic acid and carbonic acid are both relatively common acids. Carbonic acid is relatively unstable. For example, when heated, it will produce carbon dioxide and water. In terms of acidity, silicate is stronger. Silicic acid is also a relatively common acid. It plays many roles in the chemical industry and is often used as an adsorbent for gases or vapors. It can achieve the effect of decolorization and is also often used as a catalyst.

It should be: The acid is weaker than carbonic acid. Verification Method

Yes: When CO2 is passed into Na2SiO3 solution, a colloidal precipitate is formed, which proves that carbonic acid is more acidic than silicic acid. Silicic acid has low solubility in water and is weakly acidic. The acidity of silicic acid is weaker than that of carbonic acid, which can be proved by the reaction: when carbon dioxide is introduced into the silicate solution, the solution becomes turbid because an insoluble silicic acid precipitate is generated. The reaction principle is that a strong acid produces a weak acid, which means that carbonic acid is stronger than silicic acid. Silicic acid can also be easily decomposed into silicon dioxide and water. It is solid at room temperature, dissolves less, and ionizes even less. Its acidity is naturally strong like carbonic acid. It can also be obtained from the periodic table of elements. C is above Si, the highest valence oxide hydrate

Used for the adsorption of gases and steam, the decolorization of oils and waxes, and the preparation of catalysts and their carriers.

It is used as a solvent for producing tungsten wire, a chemical reagent, contact agent and adsorbent for chromatographic separation in analytical chemistry, and a raw material for manufacturing silica gel and silicate.

In analytical chemistry, it can convert insoluble fluorides such as calcium fluoride and aluminum fluoride into soluble solutions for the determination of fluorine.

Silicic acid is a glassy, ​​colorless, transparent, amorphous particle with a relative density of 2.1 to 2. It is insoluble in water and alcohol. Silicic acid has various molecular compositions, such as disilicate (H2Si2O5), metasilicic acid, orthosilicic acid (Si(OH)4 or H4SiO4), etc. The silicic acid commonly used is stable metasilicic acid H2SiO3.
