What are partially miscible liquids?
A pair of liquids is considered partially miscible if there is a set of compositions over which the liquids will form a two-phase liquid system. This is a common situation and is the general case for a pair of liquids where one is polar and the other non-polar (such as water and vegetable oil.)
What is CST and its application?
Critical solution temperature can be used to determine the purity of a substance. If there are small amounts of impurities present in CST values, the value will be impacted very strongly. It is usually a linear relationship between CST value and impurity concentration.
What is the effect of impurity on partial miscibility of liquids?
Impurity increases the mutual solution of liquids by distributing itself between the two conjugate solutions in a perfect way. Impurity constantly changed among conjugate solutions and acts as a cementing pressure whereby increasing mutual solubility of liquids.
What is the effect of temperature on solubility of partially miscible liquids?
Partially miscible liquids become more soluble with the increase in temperature and at a certain temperature they are completely miscible. This temperature is known as the critical solution temperature (CST) or consolute temperature.
What method is used to separate miscible liquid?
The method that can be used to separate a liquid from a mixture of miscible liquids with different boiling points is distillation.
How are miscible liquids separated?
The two components of the miscible liquids are separated by distillation. The difference in the boiling points of the liquids depend upon the attraction between the particles of the liquid.
What is CST explain?
Central Sales Tax or CST is imposed on sale or purchase of goods occurring the the course of inter-state trade or commerce. Value Added Tax (VAT) is applicable on purchase or sale of goods within a state, whereas CST is levied on interstate purchase or sale of goods.
What are the features of CST?
- Central Sales Tax is the tax levied on sales of goods and services.
- Central Sales Tax.
- It applies to inter-state trade only.
- Central Sales Tax is required to be paid in the state where the trade actually takes place.
- The state that collects the Central Sales Tax on inter-state trade will get to retain the same.
