Unit 5: Acid/Base Review

Front

What is a weak base?

Back

A weak base is a base that does not fully ionize in solution, resulting in a lower concentration of hydroxide ions compared to strong bases.

Front

What is the formula for calculating pH?

Back

pH = -log[H⁺], where [H⁺] is the concentration of hydrogen ions in moles per liter.

Front

What is the role of indicators in acid-base chemistry?

Back

Indicators are substances that change color at a specific pH range, helping to determine the acidity or basicity of a solution.

Front

What is the equivalence point in a titration?

Back

The equivalence point is the point in a titration where the amount of acid equals the amount of base, resulting in complete neutralization.

Front

What happens to pH at the equivalence point of a strong acid and strong base titration?

Back

The pH at the equivalence point is typically around 7, indicating a neutral solution.

Front

What is the significance of a pH of 7?

Back

A pH of 7 indicates a neutral solution, where the concentration of hydrogen ions equals the concentration of hydroxide ions.

Front

What is a strong acid?

Back

A strong acid is an acid that completely ionizes in solution, producing a high concentration of hydrogen ions.

Front

What is the relationship between pH and hydroxide ion concentration?

Back

As pH decreases, the concentration of hydroxide ions (OH⁻) decreases, and vice versa.

Front

What is the pH range of acidic solutions?

Back

Acidic solutions have a pH less than 7.

Front

What is the pH range of basic solutions?

Back

Basic solutions have a pH greater than 7.
