Exploring the Properties of Acids and Bases

This video by Mr. Millings covers the properties of acids and bases, providing examples such as citric acid in lemons and sodium hydroxide in soap. It explains the characteristics of acids, like their sour taste and ability to conduct electricity, and bases, which are bitter and slippery. The video also distinguishes between strong and weak acids and bases, emphasizing the concept of dissociation in water. Strong acids and bases fully dissociate, while weak ones do not. The video concludes with a call to subscribe and engage with the content.

Why do lemons have a sour taste?
