freezing point depression

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 f..

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 pressur..

Identify the freezing and the boiling points of water in Fahrenheit scale. => 32°F and 212°F or 37°F or 0°F and 100°F or None of the above..

Which of these are the freezing and the boiling points of water in Celsius scale? => 0°C and 100°C or 32°C and 212°C or 37°C and 100°C or None of the above..

A pole 20 m high is fixed on the top of a tower. The angle of elevation of the top of the pole as observed from a point P on the ground is 65°. The angle of depression of the point P from the top of the tower is 60°. What is the height of the tower? => 161 m or..

The angle of elevation of a cloud from a point 200 ft above a lake is 40° and the angle of depression of the reflection of the cloud in the lake is 60°. Find the height of the cloud above the lake. => 200 ft or 400 ft or 385 ft or 570 ft..

When cooled below 0 o C nitric acid freezes to a white solid, which melts at - 42 o ..

When common salt is added to crushed ice to make a freezing mixture the temperature is lowered below 0 o C. This is because ice absorbs heat from salt which is at a higher temperature and some ice melts dissolving some salt in it. This process continues till all the salt is dissolved or ..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmoti..

Colligative Properties - Certain properties of solutions depend only on the number of particles of the solute (molecule or ions) present in definite volume of the solution and do not depend on the nature of solute. Such properties are called colligative properties. A few colligative properties are:..
