Answer

Brief Explanations:

Los ácidos fuertes se disocian completamente en solución acuosa. El ácido clorhídrico (HCl) y el ácido sulfúrico (H₂SO₄) son ejemplos de ácidos fuertes, mientras que el ácido acético (CH₃COOH) es un ácido débil. Las bases fuertes se disocian completamente en solución acuosa. El hidróxido de sodio (NaOH) y el hidróxido de calcio (Ca(OH)₂) son bases fuertes, mientras que la amonía (NH₃) es una base débil.

Answer:

  1. d) Both b and c
  2. d) Both b and c
