Acids and Bases

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is pH?

Back

pH is a scale used to measure the acidity or basicity of a solution, ranging from 0 (strongly acidic) to 14 (strongly basic), with 7 being neutral.

Front

What pH value indicates a neutral solution?

Back

A neutral solution has a pH of 7.

Front

What is the strongest acid on the pH scale?

Back

The strongest acid has a pH value closest to 0.

Front

What pH value would indicate a weak acid?

Back

A weak acid typically has a pH value closer to 7, usually between 4 and 6.

Front

What is the relationship between pH and acidity?

Back

As the pH value decreases, the acidity of the solution increases.

Front

What is the relationship between pH and basicity?

Back

As the pH value increases, the basicity of the solution increases.

Front

What is a strong acid?

Back

A strong acid is one that completely dissociates in solution, producing a high concentration of H+ ions.

Front

What is a weak acid?

Back

A weak acid is one that partially dissociates in solution, resulting in a lower concentration of H+ ions.
