arrhenius concept of bases

Acid Base Equilibrium-Arrhenius Concept of Acids and Bases - Based on certain characteristic observable properties, electrolytes were classified into acids and bases..

Arrhenius Concept of Acids and Bases Arrhenius in 1887 put forward this concept. Accordingly, an acid is a hydrogen-containing compound, which gives free hydrogen ions when dissolved in water. A base is a hydroxyl group c..

A substance which dissociates in aqueous solution to give hydroxyl ions is called an Arrhenius base..

Although Bronsted-Lowry theory was more general than Arrhenius' theory of acids and bases, it failed to explain the acid-base reactions which do not involve transfer of proton. For e.g., it fails to explain how acidic oxide such as anhydrous CO 2 , SO 2 , SO 3 etc can ..

Rates of most chemical reactions increases with temperature because the rate constant 'k' increases with temperature. The temperature dependence of the rate constant is given by the Arrhenius equation, where..

Although the Bronsted-Lowry concept of acids and bases is better than the Arrhenius concept, it cannot account for the acidic and basic character of compound not containing hydrogen. For example, acidic nature of oxides such as CO 2 , SO 2 etc., and the basic..

In 1938 G.N. Lewis put forward a more generalized acid-base concept. According to this concept, an acid is a species (charged or uncharged), which can accept a pair of electrons and a base is a species (charged and uncharged), which can donate a pair of ele..

When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a hydrogen ion, it is in fact giving away a proton. Thus, the base while accepting a..

An acid is a substance which can furnish hydrogen ions in its solution. Examples: ..
