Acid and bases

Arrhenius Acid

A substance that produces hydrogen ions when dissolved in water

Arrhenius Base

A substance that produces hydroxide ions(OH⁻¹) when dissolved in water

Bronsted-Lowry acid

a hydrogen (proton) donor. The substance that remains after the hydrogen has been donated is called the conjugate base

Bronsted-Lowry base

a hydrogen (proton) acceptor. The substance that forms after the hydrogen has been accepted is called the conjugate acid

Strong acids/bases

All of the molecules will separate into ions.ALL acid molecules separate (dissociate) into [H+] ions in water; only ions present

weak acids/bases

Mostly Molecules and few ions present. Most acid molecules stay together, only a FEW separate into [H+] ions when in water; few ions present, mostly molecules.

pH scale

a logarithmic scale used to determine if a solution is acidic or basic

Properties of acids

Produce H3O+1 (hydronium ion) when dissolved in water. tastes sour. React with metals to form hydrogen gas. Neutralizes a base to form a salt and water

Properties of Bases

Produce OH-1 (hydroxide ion) in when dissolved in water.Tastes Bitter.Feels slippery. Neutralizes an acid to form a salt and water

conducts electricity: They are called ELECTROLYTES

what do both properties of acids and bases have in common

Solve for pH or pOH

Solve for [H⁺] or [OH⁻]

to relate pH and pOH

pH +pOH=14

Equilibrium constant of water

Kw = [H₃O⁺][OH⁻]=1.0 x 10⁻¹⁴
