Question
Detergent can be used with any of the following:
- Only soft water
- Only hard water
- Both soft and hard water
- Ionic solvents
Hint:
Detergents can react with minerals as well.
The correct answer is: Both soft and hard water
Detergent can be used with Both soft and hard water.
liquid detergents wash equally well in soft and hard water. Powdered detergent performed better than liquid in soft water. Water hardness affects powder detergents, and depending on the detergent type, 10-15% to 30% or more additional detergent was required to achieve results similar to soft water.
Synthetic detergents are also used in hard water because the calcium and magnesium salts of detergents are water-soluble.
Detergent dissolves more easily than soap, so it creates more lather than soap.
