Q

Strong acids/bases vs weak/bases acids

A

Strong- completely ionizes (split into atoms)(100%) when dissolved in water

Weak - Doesn’t completely ionize (<100%) when dissolved in water

Q

Acids and bases react with each other (Neutralization)

A
  1. an ionic compound (salt) is produced
  2. water is produced if the base contains hydroxide ions
  3. H+ from the acid combines with the OH- from the base

Q

Strong acid + weak base

A

Example:
Overall eqation: HCl(aq) + NH3(aq) -> NH4Cl(aq)
Produces a salt, no water.

Total Ionic equation: H+(aq) + NH3(aq) -> NH4+(aq)
Remove Cl- from both sides since it is a spectator.

Strong acid/weak base always H+ + B -> HB+

Q

Weak acid + Strong base

A

Example:
Overall equation: HF(aq) + KOH(aq) ->KF(aq) + H2O(l)
Salt + water.

Total Ionic equation: HF(aq) +OH-(aq)-> F-(aq) + H2O(l)
Remove K+ from both sides since it is a spectator.

Weak acid/strong base always: HX + OH- -> X- +H2O
