Hi is me again I just tested liquid soap, in red and blue litmus papers. the blue did not turned red which means is not acidic, but the pink looked kind of turning blue and although I try it different times it still looks like wanting to turn blue, I don't know it its because the soap is green and that might have affected the results. I would like to know if liquid soap is in fact a base just to verify my answer.
Thanks again :)
Your soap is probably neutral-they try to get it as close to neutral as possible to be gentle
Most soaps are slightly basic. The "harsh" soaps are those that haven't washed as much of the alkali out of the product. The "better" soaps have washed most of the alkali out and usually a perfume of some kind is added.
'Neutral' soaps are slightly acidic, pH 5.5 or so.
Standard soap, sodium palmitate for example, is basic as it is the salt of a weak acid and strong base.
To determine if liquid soap is a base, you can perform a simple pH test. Here's how you can do it:
1. Start by obtaining a pH test strip or pH indicator solution. These are readily available at most drugstores or online.
2. Take a small sample of the liquid soap that you want to test.
3. Dip the pH test strip into the soap or add a few drops of the pH indicator solution to the soap sample.
4. Observe the color change on the pH test strip or in the solution. Match the color to the pH scale provided with the test strip or indicator solution.
5. The pH scale ranges from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity or basicity.
6. If the pH test indicates a value greater than 7, it means the liquid soap is likely a base.
It's important to note that different liquid soaps may have varying pH levels depending on their composition and intended use. So, it's always a good idea to perform the pH test to get an accurate result.
