Acids and Bases

Front

What is an acid?

Back

An acid is a solution that contains positive ions (H+) dissolved in water.

Front

What happens to the pH when more water is added to an acidic solution?

Back

The pH will increase and get closer to 7.

Front

True or False: The higher the concentration of negative (hydroxide) ions in the solution, the stronger the base is.

Back

True.

Front

What are some common uses of bases?

Back

Bases are mainly used to make cleaning products, soaps, and concrete.

Front

Which pH value represents a base?

Back

A pH value of 8.1 represents a base.

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 ion is responsible for the acidic properties of a solution?

Back

The hydrogen ion (H+) is responsible for the acidic properties of a solution.

Front

What ion is responsible for the basic properties of a solution?

Back

The hydroxide ion (OH-) is responsible for the basic properties of a solution.

Front

What is a neutral solution?

Back

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

Front

How do acids and bases react with each other?

Back

Acids and bases react with each other in a neutralization reaction to form water and a salt.
