En la elaboración industrial de galletas es común que se agreguen crémor tártaro (khc4h4o6) y
bicarbonato de sodio (nahco3), ambos en polvo, para que, al hornearlas, estos dos compuestos
reaccionen entre sí, liberando dióxido de carbono gaseoso. el gas queda “atrapado” dentro de la
galleta horneada y eso hace que se esponje. la ecuación que representa la reacción entre los dos
compuestos mencionados, es la siguiente:
khc4h4o6(s) + nahco3(s) → knac4h4o6(s) + co2(g) + h2o(l)
la industria galletera lleya, s. a. sabe que la producción de 0.01 kg de co2 por cada kg de galletas es
suficiente para obtener un esponjado adecuado. tomando en cuenta las siguientes condiciones: - no debe quedar nahco3 en el producto terminado porque altera el sabor. - el crémor tártaro sólo se puede conseguir en una mezcla comercial “sponjex©” que por cada 100
g contiene 20 g de crémor tártaro y 80 g de leche descremada. - se recomienda que en la galleta horneada permanezca un residuo de 0.7% en peso de crémor
tártaro, para mejorar su sabor.
¿cuántos gramos de sponjex y de bicarbonato de sodio con 95% de pureza se deben emplear en la
formulación para preparar 1 kg de galletas de la mejor calidad?
