Review for Quest

• In one paragraph explain the history of industry
  on the shores of Onondaga Lake.
• NaCl used from salt brines
• Evaporated water off by fire until too expensive
  and forests depleted
• Let sun evaporate water until West did it cheaper

• Using your Solvay process summary sheet and
  solubility curve, draw your production plant and
  explain each step of the process.

Review for Quest

• If you purchased ammonia for 9 cents a gram and
  sold sodium carbonate for 9 cents per gram, how
  much money could you make for every 1000kg of NH3
  that you purchased?
• Assume 50 of NaHCO3 produced is left in solution
  and 50 precipitates out.
• Assume all the NH4Cl remains dissolved in
  solution.
• Assume your costs for employees are 20 / hour.
• Assume it takes 4 hours for 40 employees to
  produce one batch.
• Assume operating costs are 20,000 / day.
