State the label has been eaten away with age

Reference no: EM13172987

A dark glass bottle of chemicals is found in cleaning out an old basement. Part of the label has been eaten away with age. Only the last part of the label is readable. From the legible portion, the word nitrate is found. A small amount of the unknown solid is dissolved in deionized water. Sodium chloride is added to the solution. A white precipitate forms which is insoluble in nitric acid. Analyze the data and determine what cation is present in the bottle (Na+, K+, Ca2+, Fe3+, NH4+). Assuming the bottle contains only one substance, what is the name and formula for the compound in the bottle. (Think creatively)
