U6 Q1 Acids and Bases

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 an acid?

Back

An acid is a substance that donates hydrogen ions (H+) in a solution and typically has a sour taste.

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H+) or releases hydroxide ions (OH-) in a solution, usually having a bitter taste.

Front

What is the strongest acid on the pH scale?

Back

The strongest acid has a pH close to 0.

Front

What is the strongest base on the pH scale?

Back

The strongest base has a pH close to 14.

Front

What happens when an acid and a base react?

Back

They neutralize each other, typically forming water and a salt.

What is a neutral solution?

Back

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

Front

What is the characteristic taste of acids?

Back

Acids typically have a sour taste.

Front

What is the characteristic taste of bases?

Back

Bases typically have a bitter taste.

Front

What is the role of hydrogen ions (H+) in acids?

Back
