Acid-base buffers are briefly explained, as well as the buffering effect. The main point of the screencast, however, is the pH value calculation in the buffer range. Furthermore, it is described how buffer systems are formed in titrations of weak acid with a strong base. Original: "Wolfgang Dukorn"

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
An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis. An alkali
