I would argue that Carbonic acid is not a sufficient reducing agent to reduce zinc to its +2 oxidation state. It yields: 10 mM. The chemical formula for the acid is H2CO3 with a molecular weight 62.03 g/mol approximately. Rainwater infiltrating through the soil absorbs carbon dioxide from the carbon dioxide-rich soil and forms a dilute solution of carbonic acid. The stable oxidation state of phosphate ion is, (-2). Because there's a carbon atom present in this molecule, we can identify this as an organic compound. carbon-containing compound which has the chemical formula H2CO3 its chemical structure is also given below.

By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Only 26 percent of the total carbon dioxide content of blood exists as bicarbonate inside the red blood cell, while 62 percent exists as bicarbonate in plasma; however, the bulk of bicarbonate ions is first produced inside the cell, then transported to the plasma. One of the main differences between carbonic acid and sulfuric acid is the chemical formula. Carbonic acid is important in the transport of carbon dioxide in the blood. 3) Carbonic acid equilibrium. It is made up of one carboxyl group and two hydroxyl groups. 2) Carbonic acid formation.
