pH, 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 does it mean if a solution has a pH of 7?

Back

A solution with a pH of 7 is considered neutral, meaning it has an equal concentration of H+ and OH- ions.

Front

What are acids?

Back

Acids are substances that release H+ ions in solution, typically having a pH less than 7.

Front

What are bases?

Back

Bases are substances that release OH- ions in solution or accept H+ ions, typically having a pH greater than 7.

Front

What is a common property of acids?

Back

Acids often taste sour and can turn blue litmus paper red.

Front

What is a common property of bases?

Back

Bases often feel slippery and can turn red litmus paper blue.

Front

What happens to litmus paper in an acidic solution?

Back

In an acidic solution, blue litmus paper turns red.

Front

What happens to litmus paper in a basic solution?

Back

In a basic solution, red litmus paper turns blue.

Front

What is the relationship between pH and acidity?

Back

The lower the pH, the more acidic the solution is.

Front

What is the relationship between pH and basicity?

Back

The higher the pH, the more basic the solution is.
