What happens when you mix soap with acid?
It will bump the weaker fatty acid out of its place on the soap molecule and take its place. The altered molecule will then be the salt of the stronger acid. The extra fatty acids will add to the superfat.
Does hydrochloric acid dissolve soap?
About Hydrochloric Acid Hydrochloric acid is made from hydrochloride mixed with water and is a very strong chemical that can almost instantly dissolve the soap and hair that is clogging your drain.
Why do we add HCl in saponification?
In the presence of a strong base and heat, a hydroxide OH- attacks the ester and replaces OR (where R represents the fatty acid chain) with itself (OH) thereby severing the chain from the glycerol. However, HCl (or any strong acid) changes the CONDITIONS OF THE SOLUTION, making the solution neutral or acidic.
What pH is soap?
9-10
Results: Majority of the soaps have a pH within the range of 9-10. Majority of the shampoos have a pH within the range of 6-7. Conclusions: The soaps and shampoos commonly used by the population at large have a pH outside the range of normal skin and hair pH values.
Can you put HCl down the drain?
Never dispose of hydrochloric acids or any other acids or bases on the ground, in a storm drain or in a gutter, because they can contaminate groundwater, surface water and drinking water supplies.
Is hand soap an acid?
Soap is a combination of a weak acid (fatty acids) and a strong base (lye), which results in what is known as “alkalai salt,” or a salt that is basic on the pH scale. Soap is actually around the same pH as baking soda!
Is making soap a chemical reaction?
Saponification is at the heart of soap-making. It is the chemical reaction in which the building blocks of fats and oils (triglycerides) react with lye to form soap. Saponification literally means “turning into soap” from the root word, sapo, which is Latin for soap.
