Homework Answers
We can generalize very few comments on reducing the acid concentration:
(1). The acidity of the solution will decrease. Upon 100 fold the decreases will be lower but upon 1000 fold and onwards the decreases will be more and more.
(2). The reason for the decrease is the amount of H+ in the solution will be very low. Hence the acidity of the solutions will be lower.
(3) If anyone want to do any reaction in the acidic medium then the reaction will not proceed in this high dilute solution.
(4) The interesting phenomenon is that if the acid is weak a then upon dilution the activity of the solution will be higher at high dilute medium. This is because of the kohlraush high dilutions rules.
(5) The conductivity of the solutions will also increase.

The effects on Zink, Copper, Nickel, Aluminum, and Iron.

1. Marble is calcium carbonate (CaCO3). Its reaction with hydrochloric acid is CaCO3 + 2HCl CaCl2 + CO2 + H2O What was the gas produced when marble reacted with HCl? Write chemical equations for the reactions of marble with two other acids. Do these reactions have anything in common? In light of your observations, speculate on the damage to marble statues and buildings caused by acid rain. 2. What generalization can you make about the effect of changing...
