Learn the basics about the pH scale, universal indicator and litmus paper. Indicators tells if something is acidic, alkaline or neutral. Indicators are substances that show different colours when they are in acidic or alkaline conditions. Litmus paper is a simple indicator that tells us whether so
Producing custom solutions is laborious and time-consuming. Why not resort to ready-to-use mixtures or ready-to-use solutions. Ready-to-use mixtures, including special requests, can be ordered and used quickly and easily. Of course, in compliance with all legal requirements and tested quality. Fredd
