What Are Neutralization Reactions & Buffers?

Front

Neutralization reaction

Back

A reaction in which an acid and a base combine to produce a neutral solution of water and salt.

Indigestion, frequently called an upset stomach, occurs when the stomach produces excess ________ when people eat certain foods, are stressed, or have certain stomach problems.

Back

acid

What is a salt in chemistry?

Back

An ionic compound consisting of a negatively charged anion from an acid and the positive cation from a base.

Front

What is a buffer?

Back

A buffer is a solution in which the pH remains relatively constant even when small amounts of acid or base are added. It is able to resist changes in pH and typically consists of a weak acid and one of its salts, or a weak base and one of its salts.

Front

A buffer can resist changes in pH even when too much acid or base is added.

Back

False

Front

Buffer capacity

Back

Buffer capacity is the amount of acid or base that can be added to a buffer before significant changes in pH occur.

Front

Write a general word equation for a neutralization reaction.

Back

Acid + Base → Salt + Water

Front

Why can't a buffered solution absorb an unlimited amount of acid or base?

Back

A buffer can only neutralize a limited amount of added acid or base before its capacity is exceeded, after which the pH will change significantly.
