Properties of Water and pH

Front

What is the pH scale used for?

Back

The pH scale measures the acidity or basicity of a solution, indicating the concentration of hydrogen ions (H⁺) present.

Front

What is considered a strong acid on the pH scale?

Back

A strong acid typically has a pH of 1 to 3.

Front

What does a pH of 7 indicate?

Back

A pH of 7 indicates a neutral solution, where the concentration of H⁺ ions equals that of OH^- ions.

Front

What is the relationship between acids and hydrogen ions?

Back

Acids are substances that increase the concentration of hydrogen ions (H⁺) in a solution.

Front

What is the relationship between bases and hydroxide ions?

Back

Bases are substances that increase the concentration of hydroxide ions (OH^-) in a solution.

Front

What taste is commonly associated with acids?

Back

Acids typically have a sour taste, like lemon juice.

Front

What is the effect of a lower pH on acidity?

Back

A lower pH value indicates a higher acidity, meaning more H⁺ ions are present.

Front

What is the effect of a higher pH on basicity?

Back

A higher pH value indicates a higher basicity, meaning more OH^- ions are present.

Front

What is a common example of a strong acid?

Back

Common examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).

Front

What is a common example of a strong base?

Back

Common examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
