The document discusses acids and bases, including: - Acids dissociate in water, producing H+ ions. Strong acids fully dissociate while weak acids only partially dissociate. - The pH scale measures acidity and basicity on a scale from 0-14, with lower values being more acidic and higher more basic. Common pH values include lemons at 3 and lakes around 7. - Buffers resist changes in pH. The main buffer in human blood is bicarbonate, maintaining a pH of 7.25-7.35.
