Acids and Bases: pH scale Wk 11 Sp 2025

Front

What is the pH scale?

Back

The pH scale is a measure of how acidic or basic a solution is, ranging from 0 to 14.

Front

What pH value indicates a neutral solution?

Back

A pH value of 7 indicates a neutral solution.

Front

What are strong acids and bases?

Back

Strong acids completely dissociate in water, while strong bases completely dissociate to produce hydroxide ions.

Front

What is the range of pH for acids?

Back

Acids have a pH range of 0 to 6.

Front

What is the range of pH for bases?

Back

Bases have a pH range of 8 to 14.

Front

What ions do acids produce in solution?

Back

Acids produce hydrogen ions (H⁺) in solution.

Front

What is neutralization?

Back

Neutralization is the chemical reaction between an acid and a base that produces water and a salt.

Front

What is an example of a strong acid?

Back

Hydrochloric acid (HCl) is an example of a strong acid.

Front

What is an example of a strong base?

Back

Sodium hydroxide (NaOH) is an example of a strong base.

Front

What is the formula for calculating pH?

Back

pH = -log[H⁺] where [H⁺] is the concentration of hydrogen ions.
