All Sections 3) Chloride and Bromide ions are often used in swimming pools, which when reacted with an oxidizer to form HOCI or HOB – a sanitizer. Hypobromous acid works better at higher temperatures and is softer on the skin, so is more often used in hot tubs and spas. To determine the concentration of bromide ion in water, we can react the bromide ions (Brl- ) with silver nitrate to make silver bromide (solid) and nitrate ions. a) Write the balanced equation. Assume the metal paired originally with bromide ion is a group 1 metal. b) One swimming pool is found to have a concentration of bromide ion of 4.25 x 10-5 M. What mass (in g) of bromide ion would be in an Olympic sized pool which contains 2.5 x 106 L of water? The density of the pool water is 0.9978 g/mL. c) What mass (kg) of silver bromide can be precipitated (using the entire pool) by reacting (excess) silver nitrate with seawater?
