How Does the Brønsted-Lowry Theory Redefine Acids and Bases in Chemistry?

The Brønsted-Lowry theory helps us understand acids and bases better. Here's a simple breakdown:

Acids: These are substances that give away hydrogen ions (H⁺). Think of them as "proton donors."

Bases: These are substances that take in hydrogen ions. You can think of them as "proton acceptors."

Key Points to Remember:

  • pH Scale: This scale goes from 0 to 14.

    • A pH less than 7 means something is acidic.
    • A pH greater than 7 means it’s basic.
    • A pH of exactly 7 means it’s neutral (neither acidic nor basic).
  • Neutralization Reaction: This happens when an acid and a base react together. They create water and a salt. Here’s a simple formula to show this:

    Acid + Base → Salt + Water

    For example:

    HA + BOH → BA + H₂O

This theory is important because it gives us a better understanding of how acids and bases work, beyond just the basic definitions we knew before.
