salt of weak acid and a weak base

A bisalt, or an acid salt contains replaceable hydrogen ions in association with the acidic radicals. It is obtained by the incomplete replacement of hydrogen ions by metal ions or ammonium ions. Examples: NaHCO 3 , NaH 2 PO 4 and Na 2 HPO 4 . Since such salts..

The mechanism of acid-base indicator was developed by Ostwald, which offered an explanation for the colour change with change in pH. All acid-base indicators are weak organic acids or bases, which possess different colours in unionized and ionized ..

Accordingly, carboxylic acids evolve hydrogen with electropositive metals as alcohols do. Carboxylic acids react with weaker bases such as carbonates and bicarbonates to evolve CO 2..

A neutral salt arises due to the neutralization reaction. Here, salts of strong acid and strong base combine to form such salts that show a neutral pH of ..

A basic salt may also be formed by the partial replacement of the hydroxyl groups of a diacidic or triacidic base, by an acid radical. Basic salts are stronger in their basic nature and show a pH greater than ..

Such salts are formed by the intimate association of two simple salts, when crystallized from a solution of a mixture of the two. Some Common Double Salts Potassium alum Ammonium alum Ferric ammonium alum ..

Salts that contain more than one acid radical or basic radical are called as mixed salts. Some Common Mixed Salts Potassium calcium phosphate Bleaching powder Sodium potassium carbonate Sodium potassium sulph..

Calcium hydroxide, which is a base, reacts with carbon dioxide to produce a salt and water. Since this is similar to the reaction between a base and an acid, we can conclude that nonmetallic oxides are acidic in nature..

General Preparation of Salts - Salts are generally ionic compounds formed by the reaction of an acid with a base. The preparation of these salts involves the treating of different metals and non-metals and their compounds with various acids..

Salts are generally ionic compounds formed by the reaction of an acid with a base. The preparation of these salts involves the treating of different metals and non-metals and their compounds with various acids, bases etc. However, some of ..
