Weak Acids and Their Properties

The video provides a brief overview of the differences between strong and weak acids. It begins with the Bronsted-Lowry definition of acids as proton donors. Strong acids, such as hydrogen chloride, sulfuric acid, and nitric acid, are described as being nearly 100% ionized in solution, making them effective hydrogen ion donors. In contrast, weak acids like ethanoic acid do not fully ionize in water, as their reactions can proceed in both directions. The video concludes with a mention of future topics, including alcohols.

What is the Bronsted-Lowry definition of an acid?
