Hi I did some tests with the litmus paper, and I would like to know if they are correct:)
Thing tested What I got
*distilled water neutral
*liquid soap
Distilled water should be neutral. You didn't type the results of the pH test on liquid soap. It could be acid, basic, or neutral but more than likely is slightly acidic, perhaps pH 6 or so.There are some basic liquid soaps and some of about pH 6.
To determine the pH of a substance using litmus paper, follow these steps:
1. Obtain a piece of litmus paper. Litmus paper is a pH indicator that comes in red and blue strips. Red litmus paper turns blue in the presence of a base, while blue litmus paper turns red in the presence of an acid.
2. Dip the litmus paper into the substance you want to test. Make sure the litmus paper gets fully immersed.
3. Observe the color change on the litmus paper. If the red litmus paper turns blue, it indicates the substance is basic or alkaline. If the blue litmus paper turns red, it indicates the substance is acidic. If there is no change in color, the substance is likely neutral.
Based on the information you provided, the test you performed on distilled water is correct. Distilled water should be neutral, and if it did not cause any color change on the litmus paper, it is likely neutral.
However, you did not mention the outcome of the test on liquid soap. Without this information, we cannot determine the pH of liquid soap. However, it is worth noting that most liquid soaps are slightly acidic, typically around pH 6. Some liquid soaps can be slightly basic or even neutral, depending on the specific formulation. It is recommended to perform another test with litmus paper on the liquid soap to get a definitive result.
