valoración de ácido fuerte - base fuerte
Para averiguar la concentración de una disolución de NaOH tomamos una muestra de #vbas cm3, la disolvemos hasta 150 cm3 y la valoramos con otra de referencia de ácido clorhídrico #mac M, El indicador de fenolftaleina usado vira cuando hemos gastado #vac cm3 de ácido. Calcula la concentración de la disolución original de NaOH]]>

valoración de ácido fuerte - base fuerte (II)
Para averiguar la concentración de una disolución de Ca(OH)2 tomamos una muestra de #vbas cm3, la disolvemos hasta 150 cm3 y la valoramos con otra de referencia de ácido clorhídrico #mac M, El indicador usado vira cuando hemos gastado #vac cm3 de ácido. Calcula la concentración de la disolución original de Ca(OH)2]]>
