Formation of Solution:
The formation of a
solution from a solute and a solvent is a physical process, not a chemical
one. Substances that are miscible, such as gases, form a single phase in all
proportions when mixed. Substances that form separate phases are immiscible.
When the
solution is formed?
a) when solute settles down in the bottom
b) when solute precipitates
c) when solute completely dissolves
d) all of these
Which of the following is/are mixed during the formation of a solution?
a) solute
b) solvent
c) sand
d) both a and b
In which of the following solution/s, the particles are too small to be seen?
a) homogenous solution
b) heterogeneous solution
c) collide and suspension
d) all of these
In which of the following activities, we dissolve some sort of solute in a solvent?
a) making tea and coffee
b) washing our clothes and dishes
c) making lemonade

Which of the following solvent is used in the production of paints, inks and dyes?
a) water
b) alcohol
