Question

Which of the following pairs of liquids would form the most ideal solution?
(A) C3H8(I) and H2O
(B)CH3CH2OH(I) and H2O
(C)CH3CH2OH(I) and C8H18(I)
(D) C9H20(I) and C10H22(I)
(E)HNO3(I) and H2O(I)​

Answer 1

Answer:

correct answer is (E)

Explanation:

because both are reactive with each other

HNO3 +H2O -----> H3O +NO3

Answer 2

Let us solve for it

Explanation:

Out of these options : C9H20(I) and C10H22(I) forms ideal solutions .

Ideal solutions

They are those solutions that obey Raoult's law at all conditions of temperature and Pressure .

They are those solutions in which when A and B are mixed they form A-B

For  them:  A-B interactions are same as that of A-A and B-B .

For these solutions : change in heat energy on mixing is zero .

for these solutions : Change in volume on mixing is also zero .

For them graph shown by them is attached .

In the above question , out of all part E obeys these basic characteristics given above .
