I have been missing for a while. Reason being that I have been quite busy these couple of weeks. No cause for concern though. I'm fine and well.
Was reading and found out that litmus paper is just paper soaked in a litmus solution. Litmus is basically a weak acid that is red in colour. Its conjugate base is blue. So when hydrogen ions are added, by Le-Chateliers Principle, the position of equilibrium shifts and it turns red.
Cool huh?
