For an ideal solution,`Delta_(mix)V` is ……….and `Delta_(mix)H` is ………. .

For a non-ideal solution, Delta_(mix)V and Delta_(mix)H are zero.

b) i) A non ideal solution has DeltaH_("mixing")gt0 . What type of deviation does it show from Raoult's law? ii) What is an azeotrope?

Write the relation between Delta H and Delta U .

Give an example for the relation between Delta H and Delta U .

For which of the following reactions, Delta H is equal to Delta U ?

Assertion (A): Delta_(mix)H and Delta_(mix)V are zero for an ideal solution. Reason (R ): The interactions between the particles of the components of a solution are almost identical as between the particles in liquids.

A solution having Delta_(mix)H =-ve will exhibit ……….deviation from ideal behaviour.

Explain standard enthalpy of solution (Delta_(sol)H^(@)) .

Kl and CuSO_(4) solutions when mixed give :
