Litmus Test SciShow Experiments

The video explains the concept of a litmus test, both in everyday language and scientific terms. It describes pH as a measure of acidity or alkalinity, determined by the concentration of protons in a solution. The video provides a DIY method to create a litmus test using purple cabbage, which contains anthocyanin, a pigment that changes color based on pH levels. This experiment allows viewers to test the acidity or basicity of various solutions at home. The video concludes by highlighting the practical applications of this experiment.
