Question

why soap doesn't give lather with hard water? i dont want it from Google plz be fast ... and follow me ​

Answer 1

Answer:

Soap produces a good lather in “soft” water. Soft water does not contain any dissolved calcium or magnesium ions. ... Hard water contains dissolved calcium, or magnesium ions. These react with sodium stearate (soap) to produce a white or grey scum.

Soap is sodium or potassium salt of certain long chain fatty acids such as stearic acid, palmitic acid, oleic acid etc. ... Soap will not produce a lather with hard water until all the calcium and magnesium ions have been precipitated as stearates. Hard water thus wastes soap.
