ACIDS AND BASES- 2024-25

Front

What are acids and bases?

Back

Acids are substances with a pH less than 7, while bases are substances with a pH greater than 7. Both can be corrosive and can cause burns if strong enough.

Front

What does a pH level of 7 indicate?

Back

A pH level of 7 indicates a neutral solution, meaning it is neither acidic nor basic.

Front

What is the pH range for acids?

Back

The pH range for acids is from 0 to less than 7.

Front

What is the pH range for bases?

Back

The pH range for bases is from greater than 7 to 14.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, which means it is balanced and does not have acidic or basic properties.

Front

What happens to the pH of a solution as it becomes more acidic?

Back

As a solution becomes more acidic, its pH value decreases and moves closer to 0.

Front

What happens to the pH of a solution as it becomes more basic?

Back

As a solution becomes more basic, its pH value increases and moves closer to 14.

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in water, resulting in a low pH (close to 0).

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, resulting in a higher pH than strong acids.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in water, resulting in a high pH (close to 14).
