Overview of acid-base chemistry with pH scale, properties of acids and bases, and a neutralization reaction example.
A diagram illustrating acid-base chemistry, showing the pH scale from 0 to 14, with acids on the left (pH < 7) and bases on the right (pH > 7), including examples like stomach acid, lemon juice, baking soda, and ammonia, and a neutralization reaction example: HCl + NaOH → NaCl + H₂O.
