16.26 If water contains dissolved calcium hydrogencarbonate, out of soaps and synthetic detergents which one will you use for cleaning clothes ?
Synthetic detergents are preferred for cleaning cloths. This is because water contains calcium ions, these ions form insoluble salts when we add soap and get precipitated. However, synthetic detergents are working efficiently in both hard and soft water. When we add these detergents in water, these ions form soluble salts that act as cleansing agents.
