Chapter , Problem 35(choose chapter or problem)
Boilers are sometimes used to heat large buildings. Deposits of CaCO3, MgCO3, and FeCO3 can hinder the boiler operation. Aqueous solutions of hydrochloric acid are commonly used to remove these deposits. The general equation for the reaction is written below. MCO3(s) + 2H3O+(aq) M2+(aq) + 3H2O(l) + CO2(g) In the equation, M stands for Ca, Mg, or Fe. Design an experiment to determine the effect of various HCl concentrations on the rates of this reaction. Present your design to the class.
