Study Notes
Acid-Base Chemistry
- When acids dissociate in water, they release H+ ions into the solution.
pH Scale
- The pH scale measures the concentration of H+ ions in a solution, with a pH of 7 being neutral, below 7 being acidic, and above 7 being basic.
- The pH scale being logarithmic means that each step down the scale represents a tenfold increase in H+ ion concentration.
Acids and Bases
- Acids are substances that release H+ ions into a solution, such as hydrogen chloride (HCl).
- Bases are typically associated with the characteristic of releasing OH- ions into a solution.
pH Indicators
- pH indicators are substances that change color in response to changes in pH, indicating whether a solution is acidic or basic.
Effects on pH
- An increase in pH in a solution is caused by a decrease in H+ ion concentration or an increase in OH- ion concentration.
- The presence of ammonia (NH3) in a solution indicates a basic pH.
Acid Classification
- Hydrogen chloride (HCl) is classified as a strong acid due to its complete dissociation in water, releasing H+ ions into the solution.
