Answer 2

Explanation:

Determining the Strengths of Acids and Bases

Objectives:

1. Explain what dissociation constants explain about acids and bases.

Key Terms:

acid dissociation constant base dissociation constant salt hydrolysis reaction

Notes: (18-2)

You have probably noticed at some point that not all acids and bases are equally corrosive or harmful. This is because not all of them react the same in the presence of water. Acids and bases fall into the category of being either weak or strong bases on the following criteria.

Acids

Strong Weak

H+ ions transfers all in solution transfers only a portion in solution

reaction symbol g D

1M HCl g 1M H3O+ + Cl- 1M HC2H3O2 D 0.4M H3O+ + C2H3O2-

weak conjugate bases strong conjugate bases

Bases

Strong Weak

ions transfers OH- & strongly electronegative monatomic (O2-)& polyatomic (CO32- & PO43-)ions in solution transfers polyatomic ions in solution

NO3

reaction symbol g D

1M NaOH g 1M OH-

1M CaO g 2M OH-

1M NaNO3 D HNO3 + OH-

weak conjugate acids strong conjugate acids

The acid and base dissociation constant is the measure of the strength of the acids and bases.

The higher the dissociation constant the stronger the acid or base.

Since electrolytes are created as ions are freed into solution there is a relationship between the strength of an acid, a base, and the electrolyte it produces.

Strong acids and strong bases make strong electrolytes

Strong acid + Strong base neutral

Strong acid + Weak base slightly acidic

Strong base + Weak acid slightly basic

Weak acid + Weak base slightly acidic, slightly basic, neutral

Acids and bases are measured using the pH scale.

Scale is from 1 - 14

most acidic = 1

most basic = 14
