For an ideal solution of two components A & B , which of the following is true?

Options

  1. AΔ H mixing > 0 (zero)
  2. BA - B interaction is stronger than A - A   &   B - B . interactions
  3. CA - A ,   B - B   &   A - B interactions are identical
  4. DΔ H mixing < 0 (zero)

Correct answer

C. A - A ,   B - B   &   A - B interactions are identical

Step-by-step solution

When two components A   &   B form an ideal solution, the interactions A   –   A ,   B   –   B   and   A   –   B are similar due to which no heat is absorbed or released and also volume after mixing remains same.
