Presence of sodium tripolyphosphate (an additive) in synthetic detergent___________________?
Correct answer: A. Facilitates its use even in hard water (by sequestering the water-hardening Ca & Mg ions)
- A. Facilitates its use even in hard water (by sequestering the water-hardening Ca & Mg ions)
- B. Inhibits its corrosive effects
- C. Does not allow redeposition of dirt on the cleaned surface
- D. None of these
Explanation
Sodium tripolyphosphate acts as a builder by binding calcium and magnesium ions, reducing water hardness and allowing detergent to work effectively. This sequestration action is why synthetic detergents remain useful in hard water.
