Bring an informative resource to your unit on acids and bases with a video that explains strong and weak acids, pH scales, acids in solutions, dissociation, and dilution. 

An informative video provides a definition for an acid, where it falls on the pH scale, and how individuals test for them. It uses many examples with chemical equations.

Begin with what an alkali is and how they are formed through ionic compounds. It discusses pH testing and the properties of bases. The video covers three different theories and the way they react. 

Use a scientific video that begins with types of pH indicators, including pH meters, universal indicators, and litmus paper to explain titration indicators. 

Seeing red? If it was blue litmus paper, then it is an acid. Viewers learn about the pH scale through a video that shows how liquids may be tested by litmus paper and a universal indicator. 

An informative video begins by showing scholars how chromosomes are like encyclopedias. The instructor then explains and differentiates genome, chromosome, sister chromatids, nucleosomes, DNA, genes, and base pairs.
