And when the extraction with solvents with aqueous potassium mixture of ashes, saturation. Can prepare the alum crystals have the most weight is equal to 2.9857 when it reacts with concentrated sulfuric acid with a 1.5 M and when extracted with aqueous saturated ashes can prepare as much Alum to 2.8407 when reacts with concentrated sulfuric acid with a 1.5 M? It can be seen that the extract, the weight is the most mixed extract crystals between the potassium hydroxide solution saturated ashes can prepare the alum is equal to 2.9857.
