The O'Keefe's have 50 gallons of cucumbers for pickling. They have supplies of potassium hydroxide, sulfuric acid and ethanol on hand. The 1.5M KOH solution costs $5 per liter, 9 M H2SO4 solution costs $7.50 per liter, and ethanol costs $25 per liter. A 50 g jar of alum from the grocery store costs $8.59. Do you think it’s worth the time and trouble for Richard and Diane to make their own alum from discarded aluminum cans? Explain your answer showing all calculations
