Acids, Bases, and pH

prerequisite

Arrhenius Acids

Release H₃O⁺ ions into solution

Bronsted-Lowry Acids

Proton donor (donates H⁺ ions)

Strong Acids

• Ionizes completely

• -ic ending

Weak Acids

• Partially ionize

• -ous ending

Properties of Acids

• pH of 0-6

• sour

• blue to red litmus paper

• can be a strong and weak electrolyte

Arrhenius Base

Release OH^- ions into the solution

Bronsted-Lowry Base

proton acceptor (accepts H⁺)

Strong Base

• ionizes 100%

• soluble

• produces a weaker base

• Has OH^- in chemical formula

Weak Base

• partially ionizes

• insoluble

• doesn’t have OH^- in chemical formula

Properties of Bases

• bitter

• slippery

• strong/weak electrolytes

• conduct electricity

Why is pH important in relation to enzymes/proteins?

the enzyme/protein will denature and not work
