Chapter 19 - Ionic Equilibria in Aqueous Systems

Amino acids

________ exist in charged forms that are determined by the pH of the solution.

high capacity

A concentrated (________) buffer has lower pH fluctuations than a dilute buffer.

H3O+

When ________ or OH is introduced to a buffer, one component interacts to produce the other, resulting in the formation of the buffer.

Kas

Because the ________ varies by many orders of magnitude, each proton is titrated individually.

pH

The ________ is determined by the buffer- component concentration ratio; the ratio and the ________ are related.

high capacity

A concentrated (________) buffer has lower pH fluctuations than a dilute buffer.

buffer

The ________ has the greatest capacity when the pH of the ________ equals the pKa of the acid component.

sodium ion

The ________ is a spectator ion since it does not interact with water (as shown in the image attached)

H3O+

When ________ or OH is introduced to a buffer, one component interacts to create the other, resulting in just a small change in [________] (and pH)
