How to determine the pH of dark organic liquid?
Thread Content
Dear sea friends, as the title suggests, it’s a dark-colored organic liquid that is quite viscous and insoluble in water. How can its pH be determined? The simpler the method, the better, thank you!
The simplest method is to try inserting a pH meter electrode into this medium to see if any data can be measured. There are too many complex methods to discuss generally.
For a simple test, use a pH strip! For precision, use a pH meter!
The material is too sticky and its color is dark, so it’s impossible to determine the pH using a pH test strip. What is the range of use for a pH meter?
It is usually glass. I don’t know what medium you are?
Organic waste, with a complex composition; at room temperature, it appears as a dark brown, viscous substance.
Generally, pH meters are made of glass, but there are also plastic ones; as long as the medium in question does not react with them, they can be used.
Just use a test strip; the color change doesn’t occur as quickly, so it’s possible to determine the pH value preliminarily. If you don’t believe it, give it a try

Using a pH meter is a good method.
