Soap reacts with hard water because of the sodium ions linked with the fatty acids chain reacts with the calcium and magnesium ions in hard water. The functional group in a detergent is SO3 Na and this does not react with the calcium and magnesium ions in hard water
Detergent are better cleansing agent than soaps because they do not form insoluble calcium and magnesium salt with hard water and hence can be used for washing even with hard water
