Acid/Base Theories
There are three main theories used to explain the chemistry of acids and bases.• Arrhenius • Bronsted-Lowery• Lewis
![Page 21: Do Now … Hydroxide (NaOH) Strong base used in production of paper, textiles, and detergents. Manufactured by electrolysis of an aqueous solution of sodium chloride. Sodium Hydroxide](https://reader030.vdocument.in/reader030/viewer/2022013110/5b0e05517f8b9a2c3b8e107d/html5/thumbnails/21.jpg)
pH
pH
H is for H+ ions

Sodium Hydroxide](https://reader030.vdocument.in/reader030/viewer/2022013110/5b0e05517f8b9a2c3b8e107d/html5/thumbnails/22.jpg)
Arrhenius Acids and Bases
Acids produce hydrogen ions (H+) in aqueous solution.
Bases produce hydroxide ions (OH-) when dissolved in water.
Limited to aqueous solutions.
Only one kind of base (hydroxides).
![Page 23: Do Now … Hydroxide (NaOH) Strong base used in production of paper, textiles, and detergents. Manufactured by electrolysis of an aqueous solution of sodium chloride. Sodium Hydroxide](https://reader030.vdocument.in/reader030/viewer/2022013110/5b0e05517f8b9a2c3b8e107d/html5/thumbnails/23.jpg)
Example: Arrhenius Acids and Bases
Acid: HCl (g) H+(aq) + Cl- (aq)
Base: NaOH(s) Na+(aq) + OH-(aq)
hydrogen ion
hydroxide ion

Bronsted-Lowery Acids and Bases
An acid is hydrogen-ion donor (H+ or proton).
A base is hydrogen-ion acceptor.
Acids and bases always come in pairs.
This theory has broader applications than Arrhenius.

Bronsted-Lowery Acids and Bases
Water can act as an acid or base.
As an acid it donates protons (H+) when in a base.
As a base it accepts protons when in an acid.
