Acids and Bases Neutralization

Acid/Base Neutralization

In this lesson, you will learn about Acid/Base Neutralization Reactions

What is neutralization?

Neutralize-

The word neutralize means to cancel out.

For example, if you "neutralize" a situation, it means you calm everyone down and "cancel out" the problem.

Neutralizing Acids and Bases

Example

A neutralization reaction is a reaction where an acid and base react to form water and salt. It turns the solution neutral, so the pH will be 7!

Neutralization Reaction

Multiple Choice

In order to neutralize an acid, you need...

• Water

• Salt

• A base

• Another acid

Multiple Choice

When an acid and a base react, it always forms...

• Water and Salt

• A different acid and base

• Salt and a base

• Water and an acid

Multiple Choice

The pH of a neutral solution will be...

• 14

• 1

• 7

• 8

Indicators

Help us determine the pH

Using an indicator can tell us the pH of a substance and/or whether or not it's an acid or base.

A universal indicator is a solution we add to an acid/base to help us determine the pH. When you add it, the solution changes color and then you compare it to a chart like the one above.

Multiple Choice

Identify the salt in the following equation:
Zn(OH)₂ + HNO₃   ---> H₂O  + Zn(NO₃)₂

• Zn(OH)₂

• HNO₃

• H₂O

• Zn(NO₃)₂

Multiple Choice

What might happen if you mixed a strong acid with an equally strong base?

• You would see an explosive chemical reaction.

• The acid would destroy the base.

• The base would destroy the acid.

• You'd wind up with a pH-neutral substance.
