Important Questions on Solutions
Consider the following statements about Tincture of Iodine:
It is an antiseptic solution.
Iodine is kept in alcohol-water mixture.
Concentration of iodine is very low.
How many of the above statements is/are correct?
Radha prepared a solution which could be separated by filtration.
(i) Name the type of solution
(ii) Is the solution transparent or opaque?
(iii) Mention the nature of the solution.
(iv Mention the size of the solute particles.
It has been observed that solid solubility depends on the nature of the solute as well as the solvent. We often see that substances like sugar, common salt, etc readily dissolve in water while substances like naphthalene do not dissolve in water. From the various observations and experimental results, it has been seen that only polar solutes tend to dissolve in the polar solvent and non-polar solvents dissolve only non-polar solutes. Hence, the nature of the solvent can be seen as one of the prominent factors affecting solubility. The above observation led to the statement that like dissolves like, that is polar solvents will dissolve polar solutes and non-polar solvents dissolve non-polar solutes.
Maximum amount of a solid solute that can be dissolved in a given amount of a liquid solvent does not depend upon
