Question 1 Report

One advantages of detergents over soap is that detergents?
Answer Details
Detergents have an advantage over soap because they are able to form soluble salts with hard water. Hard water contains dissolved calcium and magnesium ions which react with soap to form insoluble scum. Detergents, on the other hand, are able to form soluble salts with these ions and do not react to form scum. This makes detergents more effective for cleaning in hard water areas. The other options listed do not accurately describe an advantage of detergents over soap.
