I been working with acids and bases for quite some time now, and though this is not as precise as using a pH meter, it is a lot more accurate than the natural indicating solution of red cabbage. And if it answers your question, 7 is neutral, below seven is acidic, above 7 is basic.

Works great! Lemon juice is red and drain cleaner dark brown

Works great! Lemon juice is red and drain cleaner dark brown, just as the bottle paper shows. Nice indicator on this litmus. I was going to make my own but this is a time saver. Thanx for selling it!
So i had this no name drain cleaner i thought was a rip off liquid, i tested a few drops left over after finishing with it. The drain cleaner pH checked out as a high base, dark brown color on the litmus, with my new Litmus paper! :)

It does not change colour to any chemical. It only gets the wet look.
