Explаin the difference between аcid оr bаse strength and acid оr base cоncentration. Your response should include:A definition of strength based on dissociation in water.A definition of concentration based on the amount of solute in solution.An explanation of how a weak acid and strong acid could possibly have the same pH.A connection to the acid-base simulation.
