# High School Chemistry : Help with Acid-Base Reactions

## Example Questions

### Example Question #1 : Help With Acid Base Reactions

What volume of a 1.2M solution of hydrochloric acid is needed to neutralize 50mL of a 3M sodium hydroxide solution?

Explanation:

The equation to use here is:

Here,  is the molarity of the acid,  is the volume of the acid,  is the molarity of the base, and  is the volume of the base. Don't forget to convert the volume to liters!

### Example Question #22 : Acids And Bases

What kind of reaction is an acid-base neutralization reaction?

Double-replacement

Oxidation-reduction

Single-replacement

Decomposition

Double-replacement

Explanation:

Below is a generic acid-base neutralization reaction:

The products are always water, and a salt. This salt is produced from the resulting ions  and . The  from the acid replaces the  from the base, and the  from the acid replaces the  from the base. Since there are two replacements, acid-base neutralizations are classified as double-replacement reactions.

### Example Question #23 : Acids And Bases

Which of the following is the definition for an Arrhenius acid?

A substance that increases the  concentration when added to water

None of these

A proton donor

A substance that increases the  concentration when added to water.

A proton acceptor
