When washing oily clothes using well water rich in dissolved calcium and magnesium salts, traditional soap forms a sticky scum and fails to clean properly, while synthetic detergent works efficiently. Why?
Soap neutralizes the acid present in hard water, preventing bubble formation.
Synthetic detergents do not form insoluble scum with calcium and magnesium ions in hard water.
Synthetic detergents convert hard mineral salts into natural gas bubbles.
Soap chemically reacts with oil to create hard mineral crystals that adhere to fabric.
Solution
Hard water contains calcium and magnesium ions that combine with soap to form insoluble scum. Synthetic detergents do not form scum with these ions and remain effective.
