Which base is present in soap?
Sodium hydroxide
Soap is produced by saponification — the hydrolysis of fats or oils (triglycerides) with a strong alkali to yield the sodium/potassium salt of a fatty acid (soap) and glycerol.
Hard bar soaps use sodium hydroxide (NaOH), the only strong alkali among the choices. Silicon dioxide (SiO2) is an acidic oxide (sand), calcium hydroxide gives insoluble "scum" soaps unsuitable for washing, and ammonium hydroxide is too weak and volatile for saponification. Hence the base in soap is NaOH.
