Since a perfectly neutral liquid such as distilled water has a pH of 7, a liquid with a pH of 7.1 is just very slightly alkaline. Perhaps it has a bit of soap in it.
The approximate pH scale of washing up liquid is 9.4.
2.5
liquid muriatic acid
12-13
The pH level must rise
It indicates that the liquid is an acid.
use to test the acid level in liquid.
Place a piece of Ph paper in the liquid and remove. The color the paper turns will tell you the acid level.
6 to 8 extream ph levels such 2, 11 causes irritating skin...

7. Most dishwashing liquids are neutral.
Phosphorus trichloride (PCl3) is a covalent compound and does not have a pH level. pH is a measure of the acidity or alkalinity of a solution and is applicable to aqueous solutions. PCl3 is a liquid compound and not soluble in water, so it does not have a pH value.
