Which statement is true about an aqueous medium________________?
Correct answer: C. Ions and molecules move randomly thus are in more favorable state to react with other molecules and ions
- A. Ionic as well as non ionic substance in aqueous media retains their identity
- B. Enzymes can not perform catalysis reaction in this medium
- C. Ions and molecules move randomly thus are in more favorable state to react with other molecules and ions
- D. It is less favorable media for chemical reactions
Explanation
In an aqueous medium, dissolved ions and molecules move freely and randomly, increasing the opportunities for effective collisions and chemical reactions. Students may choose that aqueous media are less favourable, but water is the main solvent for most cellular reactions and allows enzymes to function.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
