Oxyacid - Carbonic acid and carbonate salts | Britannica
Oxyacid - Oxyacid - Carbonic acid and carbonate salts: Carbonic acid (H2CO3) is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water. CO2 + H2O ⇌ H2CO3 The predominant species are simply loosely hydrated CO2 molecules. Carbonic acid can be considered to be a diprotic acid from which two series of salts can be formed—namely, hydrogen carbonates, …

Ca-alginate is more resistant to degradation than alginic acid. Acidifiion: The bleached calcium alginate gels are treated with dilute sulfuric acid or hydrochloric acid solution (0.5 M) to convert Ca-alginate into alginic acid by a three-step counter current conversion.
How does copper oxide and sulphuric acid react to …
Mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt. Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate.

Sample Preparation Guides
Be metal is not affected by water or cold nitric acid. It''s readily soluble in NaOH, HCl, hot nitric acid and in dilute sulfuric acid. BeO Beryllium oxide finds useful appliions in refractory crucibles because of its high melting point (2570 C) and good resistance to
Rates Of Reaction: Hydrochloric Acid + Calcium …
Aim: To investigate the rate of reaction between Calcium Carbonate (CaCo3) and hydrochloric acid (HCl) by changing the molarity of the acid and measuring how much Carbon Dioxide (Co2) is produced. Hypothesis: I predict that the higher the molar concentration of the acid the faster the reaction will take place therefor creating more gas in a shorter amount of time.
Potassium permanganate and sulfuric acid, when coined, form manganese heptoxide. Although both potassium permanganate and sulfuric acid are widely used in industrial settings, manganese heptoxide has few known uses, according to the U.S. Environmental Protection Agency (EPA).

How to Dilute Acid | Sciencing
By contrast, adding acid to water creates a small pool of dilute acid at the moment of contact. The reaction is still exothermic but releases little heat. The chance for bubbling and splashing is greatly reduced, and the dilute acid produced is less harmful than in the prior situation.
Safety Precautions with Sulfuric Acid - Nsb Notes
As sulfuric acid is very exothermic (when dissolving in water), several safety precautions are taken with the handling, storage, dilution and transportation of sulfuric acid. Water placed in sulfuric acid is extremely dangerous, as the water completely ionises small amounts of water in concentrated amounts of sulfuric acid will boil and form an acidic mist which is highly acidic and damaging
