Acids and Bases Intro

Front

What is the pH scale?

Back

The pH scale ranges from 0 to 14 and measures how acidic or basic a solution is.

Front

What pH value indicates a strong acid?

Back

A pH value of 0 to 3 indicates a strong acid.

Front

What pH value represents an acid?

Back

Any pH value below 7 represents an acid.

Front

What can burn you if they are strong enough?

Back

Both acids and bases can burn you if they are strong enough.

Front

What does the pH value of an acid represent?

Back

The pH value of an acid represents its concentration of hydrogen ions in the solution.

Front

Which ion is responsible for the properties of acids?

Back

The hydrogen ion (H+) is responsible for the properties of acids.

Front

What is a base?

Back

A base is a substance that can accept hydrogen ions (H+) or donate electron pairs.

Front

What pH value indicates a strong base?

Back

A pH value of 11 to 14 indicates a strong base.

Front

What is the neutral pH value?

Back

The neutral pH value is 7, which indicates a neutral solution like pure water.

Front

What is the relationship between pH and hydrogen ion concentration?

Back

As the pH decreases, the concentration of hydrogen ions increases.
