Question

An example of a solution which is not in equilibrium is:

• A. chemical pH indicator
• B. acid/base buffer
• C. anhydrous solution
• D. hypotonic solution
• E. supersaturated solution

Answer 1

The correct option is E supersaturated solution

In a supersaturated solution, the amount of solute in the solvent is greater than the amount that solvent can dissolve. equilibrium exists when the dissolution and crystallization continue as long as excess solute is present which is analogous to vapor pressure which happens only in a saturated solution.
