Residue on ignition means the sample is ignited at higher
temperature in the muffle furnace for the period of time.
If it is not converted as a complete ash(grey colour)add
dilute sulphuric acid to the residue and evaporate the
acidic solution again keep into the furnace to convert ash
is called sulphated ash.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
