carbon dioxide
Dissolved in water, e/g/ atmospheric CO2 into rain-water.
The forests that grows over the limestone forms mulch that produces the acid required. That's true but the prime solvent is Carbonic Acid: atmospheric carbon dioxide dissolved into rain-water.
Acid
Aqueous hydrogen chloride is a solution of hydrogen chloride gas dissolved in water. It forms hydrochloric acid when dissolved in water. It is a strong acid.
The compound responsible for the acidity of rainwater and soil is sulfur dioxide (SO2) dissolved in water, which forms sulfuric acid (H2SO4). This process is known as acid rain.
This would be carbon dioxide. When carbon dioxide dissolves in water (as all gases do to some extent) it forms carbonic acid, because the chemical formula would be in perfect balance. Carbonic acid has the chemical formula H2CO3. Also carbon dioxide dissolves into water more readily than many other atmospheric gases. CO2 + H2O <--> H2CO3
Boric acid don't react with water but is soluble in water.
When SO2 dissolves in water, it forms sulfurous acid (H2SO3). This acid is a weak acid that can dissociate into bisulfite ions (HSO3-) and hydrogen ions (H+).
Sulfur dioxide dissolves in water to form sulfurous acid (H2SO3).
If a substance dissociates and forms an excess of H+ ions when dissolved in water, it is referred to as an acid. Acids are substances that donate protons when dissolved in water, leading to an increase in H+ ions concentration in the solution.
Yes, nitrogen tetroxide is acidic. When dissolved in water, it forms nitric acid, which is a strong acid.
When an acid is dissolved in water, it forms ions such as hydronium ions (H3O+) and the corresponding conjugate base. The extent to which an acid dissociates in water depends on its strength.
