Colligative Properties - Depression in Freezing Point
Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pressure. fig 3.10 The curves..

(b) Volume of an object lighter than the liquid, which will float in the liquid
If the object is lighter, it will float on water. In that case its volume can be found out with the help of a sinker. Pour some water in a measuring cylinder and lower the sinker (any body which sinks) into it. Note the level of water. Volume of a floating body using sinker Tie the object to t..

Physical Properties
Dimethylether and ethyl methyl ether are gases at ordinary temperature. The other lower homologes are colourless, pleasant smelling, volatile liquids with typical ether smel..
Properties of Ethanol
Physical Properties - Ethanol is a colorless, inflammable liquid has a spirituous odour and burning taste. Ethanol boils at 351.1K, freezes at 155K, mixes with water in all proportions and is readily oxidized by the system when consumed internally and therefore is a source of en..
Physical Properties
Acetic acid is a colorless, corrosive liquid with a pungent smell at ordinary temperatures. But below 290K, it solidifies to an icy mass called glacial acetic acid. It boils at 391K and its specific gravity is 1.08 at 273K. It is miscible with water, alcohol and ether in all ratios. It i..
Physical Properties
Ethanol is a colorless, inflammable liquid has a spirituous odour and burning taste. Ethanol boils at 351.1K, freezes at 155K, mixes with water in all proportions and is readily oxidized by the system when consumed internally and therefore is a source of energy. It can be dried over anhy..
Electrical properties
Electrical conductivity varies from 10 8 Ohm cm - 1 in metals to 10 - 1 2 ohm - 1 cm - 1 in insulators. Based on their conductivity solids can be divided into three categories. (a) Conductors (b) Semiconductors (c) Insulato..
Physical properties
Pure CS 2 is colorless, flammable and volatile liquid. However, impure carbon disulphide has yellowish color and bad odor due to the impurities of sulphur and hydrogen sulphide. It is highly volatile (b.p.46C). It is very poisonous and can have disastrous effects on the nervous s..
