salt of weak acid and a weak base

Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..

A basic salt is formed by the action of an acid with higher proportion of the base, than is necessary for the formation of a normal salt. Example: Basic copper carbonate CuCO 3 .Cu(OH) 2 Basic lead carbonate (white lead) PbCO 3 .Pb(OH) 2 A basic salth..

On heating, hydrous crystals lose their water of crystallization and turn into a powder. They are then said to be anhydrous. Sometimes they may also lose their colour. ..

.9 - Base Pairing in DNA The nitrogen bases of the two opposite chains exhibit highly specific base pairing. A purine in one chain always pairs with a pyrimidine in the opposite chain. Among purines adenine(A) pairs only with the pyrimidine thymine (T)and vice versa. S..

Boric acid is a very weak monobasic acid, (K a = 1x10 - 9 ). It behaves as a Lewis acid accepting a hydroxyl ion,..

Hydrogen peroxide is a weak acid. For the equilibrium, ..

Bases combine with acids to form salt and water only. Base + Acid Salt + Water ..

+ ions in solution, are called weak acids. Example: CH 3 COOH, (COOH) 2 , H 3 PO 4 , HCN, HF, etc. The K a or K 1 values of such acids are much smaller than one. On dilution, the ionization of an acid increases. So, concentration of H + ions also incre..

Acidic oxides are the oxides of non-metals. When combined with water, they produce acids, e.g., ..

Sulphuric acid ionizes almost completely in water. Hence it acts as a strong acid. It also behaves as a strong electrolyte. Pure sulphuric acid is a weak electrolyte as it hardly has any water to form hydronium ions. When diluted with water, it ionizes ..
