Problem 21SE

The article “Factorial Experiments in the Optimization of Alkaline Wastewater Pretreatment” (M. Prisciandaro, A. Del Borghi, and F. Veglio, Industrial Engineering and Chemistry Research, 2002:5034–5041) presents the results of an experiment to investigate the effects of the concentrations of sulfuric acid (H2SO4) and calcium chloride (CaCl2) on the amount of black mud precipitate in the treatment of alkaline wastewater. There were three levels of each concentration, and two replicates of the experiment were made at each combination of levels. The results are presented in the following table (all measurements are in units of kg/m3).

                           

a. Construct an ANOVA table. You may give ranges for the P-values.

b. Is the additive model plausible? Explain.

c. Can you conclude that H2SO4 concentration affects the amount of precipitate? Explain.

d. Can you conclude that CaCl2 concentration affects the amount of precipitate? Explain.

Chemistry of Solutions Lecture no. 7 Thursday, September 15, 2016 Topics Covered: Le Châtelier’s principle, the nature of acids and bases, acid strength, the pH scale, and calculating the pH of strong acid solutions. Le Châtelier's Principle If a change is imposed on a system at equilibrium, the position of the equilibrium will shift in a direction that tends to reduce that change. A chemical reaction is not a sentient being, if a substance is added the rates of the forward and reverse reactions are disturbed. The net reaction occurs in one direction, until the system reaches equilibrium again, At the new equilibrium position, the reactants and products have different concentrations (compared to their initial concentrations). 1. Changing co
