1.Would you describe pH = 5.9 as a strong or a weak acid? Why?
2.Would you describe pH = 13.2 as a strong or a weak base? Why?
3.Where does a neutral solution fall on the pH scale?
4.Acids have a high concentration of (H+ / OH-) and bases have a high concentration of (H+ / OH-).
5.The diagram shows a solution of HCl. Identify HCl as an acid or a base and explain your answer!
1.Describirias pH = 5.9 como un acido fuerte o debil? Por que?
2.Describirias pH = 13.2 como una base fuerte o debil? Por que?
3.Donda se cae una solucion neutral en la escala de pH?
4.Acidos tienen una alta concentration de (H+ / OH-) y bases tienen una alta concentration de (H+ / OH-).
5.El diagrama muestra una solucion de HCl. Identifica HCl como un acido o una base y explica tu respuesta!
