Strong Acid and Weak Acid

An acid and a base are strong when they are completely ionized that is in the ionization process they are completely transformed into cations or positive ions and into anions. Now weak acids or week.

A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water.

. It always loses H when dissolved in water. In fact about only one per cent of ethanoic acid molecules split up to form H ions and CH 3 COO ions at any one. BOH H 2 O B aq OH - aq Examples of strong acids and bases are given in the table below.

It reacts with water to produce hydroxonium ions and ethanoate ions but the back reaction is more successful than the forward one. Weak acids such as ethanoic acid CH 3 COOH do not fully dissociate. Weak acids ionise partially in an aqueous solution.

Acids can be classified as strong or weak based on the concentration and their ability to react with other. Weak acid is an acid that ionizes partially. It loses less H when.

Ethanoic acid is a typical weak acid. HA H 2 O A - aq H 3 O aq Strong base. It always loses a proton H when dissolved in water.

Why do reactions of mixing strong acid and strong base differ from the reaction of mixing weak acid and weak base. Lets denote the total. The strongest acid is sulfuric acid which has a pH of 0.

A classification based on acidity constants or pK a values seems natural. Strong acids and weak acids are. Strong acids dissociate completely in water while weak acids do not dissociate completely.

To determine the volume of a strong acid HCl and weak acid CH 3 COOH in the given unknown solution and to estimate the amount of HCl and CH 3 COOH. With lowest energy species. This article will discuss strong acids and weak acids their definition and functions in the world and how they are seen from the viewpoint of science.
