Study Notes

Acids and Bases

Acids are substances that donate a proton (H+ ion)
Bases are substances that accept a proton (H+ ion)

Ionization of Hydrochloric Acid

The chemical equation for the ionization of hydrochloric acid is: HCl + H2O → H3O+ + Cl-

Electrolytes

Electrolytes are substances that dissociate into ions when dissolved in water, allowing them to conduct electricity
Examples of electrolytes include acids and bases

Identifying Acids and Bases

An acid is a substance that increases the concentration of H+ ions in a solution
A base is a substance that decreases the concentration of H+ ions in a solution
Examples of acids include hydrochloric acid (HCl) and nitric acid (HNO3)
Examples of bases include sodium hydroxide (NaOH) and calcium hydroxide (Ca(OH)2)

Ionization of Sodium Hydroxide

The chemical equation for the ionization of sodium hydroxide is: NaOH → Na+ + OH-

Commonalities between Acids and Bases

Both acids and bases can dissociate into ions when dissolved in water
Both acids and bases can affect the pH of a solution
