Academics

To isolate the barium ion the hydrate was reacted with sodium carbonate to from a white precipitate of barium carbonate. Data from this reaction is given below:

Initial mass of hydrated barium hydroxide: 0.471g

Mass of barium carbonate precipitate collected: 0.295g

To determine the amount of water present in the hydrate another sample of the hydrate was weight and heated in a crucible until the mass no longer changed. Data from this procedure is given below:

Mass of empty crucible: 10.281g

Mass of crucible + hydrate: 12.621g

Mass of crucible + anhydrous substance after heating: 11.553g

Use the data given above to determine the empirical formula of the hydrate.

· Determination of % barium

· Determination of % water

· Determination of % hydroxide

· Determination of empirical formula
