Acids and Alkalis: Understanding pH and Indicators

The video tutorial covers the basics of acids and alkalis, explaining their properties and how they interact in solutions. It introduces the pH scale, detailing how it measures acidity and alkalinity, and describes the use of indicators like litmus paper, methyl orange, and phenolphthalein to determine the pH of a solution. The tutorial also discusses the practical applications of these concepts, such as in titrations, to identify when a solution is neutralized.

How can we determine if a solution is neutral based on the pH scale?

Describe how litmus paper can be used to identify acidic and alkaline solutions.

What color changes occur with methyl orange in acidic and alkaline solutions?
