What does it mean to be 100% ionized?
What does it mean to be 100% ionized? When weak neutral acids and bases are put in water, they form ions. This is the percentage of the compound that has ionized (dissociated). Strong acids (bases) ionize completely so their percent ionization is 100%. What does it mean when a weak acid is ionized? A weak […]
