Strengths of Acids and Bases

Concentration is

• the amount of solute in the solvent

• the amount of solvent in the solute

• a measure of how strong an acid or base is

• the size of the particles in a solution

Strong acids and bases...

• do not break apart into ions (non-electrolyte)
• partially break apart into ions (weak electrolyte)
• completely break apart into ions (non-electrolyte)
• completely break apart into ions (strong electrolyte)

What are the weak acids and bases?

• all acids and bases are weak
• if not classified as strong, the acid/base is considered weak
• all acids and bases are strong
• there are more strong acids and bases than there are weak acids/bases
