Addition of concentrated sulfuric acid to potassium permanganate gives Mn 2 O 7. [76] Although no reaction may be apparent, the vapor over the mixture will ignite paper impregnated with alcohol. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidizing power and rapidly oxidizes the alcohol, causing it to ...
2 + 8 MnO 2 + H + + 4 H 2 O + 9 Cl −. In an acidic solution, permanganate(VII) is reduced to the pale pink manganese(II) (Mn 2+) with an oxidation state of +2. 8 H + + MnO − 4 + 5 e − → Mn 2+ + 4 H 2 O. In a strongly basic or alkaline solution, permanganate(VII) is reduced to the green manganate ion, MnO 2− 4 with an oxidation state ...
Permanganic acid (or manganic(VII) acid) is the inorganic compound with the formula H MnO 4 and various hydrates. [3] This strong oxoacid has been isolated as its dihydrate. It is the conjugate acid of permanganate salts. It is the subject of few publications and its characterization as well as its uses are very limited.
The measurement of pH can become difficult at extremely acidic or alkaline conditions, such as below pH 2.5 (ca. 0.003 mol/dm 3 acid) or above pH 10.5 (above ca. 0.0003 mol/dm 3 alkaline). This is due to the breakdown of the Nernst equation in such conditions when using a glass electrode.

A special case of the acid-base reaction is the neutralization where an acid and a base, taken at the exact same amounts, form a neutral salt. Acid-base reactions can have different definitions depending on the acid-base concept employed. Some of the most common are:
