The high acid rain which falls in the Northeast frees aluminum ions from the soils. The tree absorbs the aluminium ion. The sap is basic so the aluminium ion becomes aluminum hydroxide. Aluminium hydroxide is a large bulky molecule that plugs the water/nutrient transport system of the tree and ends up coking the tree to death. It is believed 0.031 grams of aluminum chloride will poison a tree. How many moles are present?
mols = grams/molar mass.
