pH Scale

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

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

Back

The pH at the equivalence point is usually neutral, which is 7.0.

Front

What does a pH of 7.0 indicate about a solution?

Back

A pH of 7.0 indicates that the solution is neutral, meaning it is neither acidic nor basic.

Front

What happens to the pH of a solution when H+ ions are added?

Back

The pH of the solution would go down, indicating an increase in acidity.

Front

What is a characteristic of bases?

Back

Bases feel slippery to the touch.

Front

What taste do bases typically have?

Back

Bases usually have a bitter taste.

Front

What is the result of mixing a strong acid with an equally strong base?

Back

You'd wind up with a pH-neutral substance.

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 does a pH less than 7 indicate?

Back

A pH less than 7 indicates that the solution is acidic.
