why do salt crystals grow faster than sugar crystals

Large, well formed crystals can be obtained, by the slow evaporation of a cold and saturated solution of the substance. A large crystal can be grown by suspending a small well formed crystal, in a cold and saturated solution of the substance. The solution must be taken..

This technique is used for obtaining a compound in pure solid form of well-defined geometrically shaped crystals. This process of crystallization can be used for the purification of a compound only when the compound and the impurities present in it differ considerably in their s..

When crystals of certain salts are formed, they do so with a definite number of molecules of water, chemically combined in a definite proportion. Water of crystallization is the number of water molecules, chemically combined in a definite molecular proportion, wi..

When certain salts form crystals with a definite number of molecules of water, they chemically combine to do so in a definite proportion. Thus, the water of crystallisation is the number of water molecules that combine chemically in definite molecular proportion, with the ..

This method is used to separate two or more solutes, by making use of their difference in solubility. If we want to separate potassium nitrate from a mixture that contains about 80 g of potassium nitrate and 20 g of sodium chloride. We will dissolve this mixture in about 100 g of water and then hea..

1. A saturated solution of copper sulphate is prepared in water at about 70 o C to 80 o C. The solubility of copper sulphate in this temperature range is about 47 - 51g. The solution is slowly and carefully cooled to room temperature. (The solubility is 25 g at 30 o C). Good quantities of cry..

Certain substances like sodium chloride do not require the help of water to form their crystalline shape. These salts are: i) Chlorides of potassium, sodium and lead. ii) Bromides of potassium, sodium, lead and silver. iii) Iodides of silver and lead. iv) Nitrates of potassium, sodium, l..

Defects in Crystals - According to third law of thermodynamic it is only at OK that true crystals passes perfect order of arrangement of atoms in pure crystals. But with rise in temperature some derivations from complete order takes place. Presence of impurities also a..
