What is a balanced chemical equation for the reaction

Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and evolve hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it ches fire and burns with a characteristic orange colour.

What is Carbonic Acid? - Definition from Corrosionpedia

Carbonic acid is an inorganic compound with the formula H 2 CO 3.It is comprised of water and carbon dioxide. Carbonic acid has a molar mass of about 62 g/mol. Carbonic acid, while relatively weak when compared with other acids, can cause corrosion depending on the chemical composition of the material.

But carbonic acid is highly unstable in normal atmospheric pressure, it decompose into water and carbon dioxide that’s why carbonate drinks produces gas when it is open. After that chloride ions reacts with the metal ions forming salts.

Corrosion of Steel Alloys in CO2 Environments

The corrosion rate of iron in a CO2 environment is not constant, especially in laboratory studies in which the starting point is a bare metal surface on a test specimen. Steel, when initially exposed to a carbonic acid solution, corrodes rapidly at first and then the rate decreases as the carbonate scale forms.

The Chemistry of Acid Rain - lardbucket

2013-9-7 · To understand acid rain requires an understanding of acid–base reactions in aqueous solution. The term acid rain is actually somewhat misleading because even pure rainwater collected in areas remote from civilization is slightly acidic (pH ≈ 5.6) due to dissolved carbon dioxide, which reacts with water to give carbonic acid, a weak acid:
