Use the Nernst Equation and the measured cell voltage to calculate the concentration of uncomplexed Cu2 in the anode compartment of the cell after reaction with NH3. This is the equilibrium concentration of the Cu2 ion that will be used to calculate Kf for the complexation reaction.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
