1. Lakes that have been acidified by acid rain can be neutralized by liming, the addition of limestone (CaCO3). How much limestone in kilograms is required to completely neutralize a 5.8×109 L lake with a pH of 5.7? Express your answer using one significant figure. 2. For each strong base solution, determine [OH−], [H3O+], pH, and pOH. 0.0412 M Ba(OH)2 3.9×10−4 M KOH 2.5×10−4 M Ca(OH)2

6. Limestone can be considered to be essentially pure calcium carbonate. Acid rain can be considered to be sulfuric acid. When limestone buildings are eroded by acid rain the reaction can be summarized by the chemical equation below. CaCO+ HISO. Caso + CO.

PROCEDURE CAUTION!!! Nitric acid and sulfuric acid are strong and corrosive acids. For that reason, avoid inhaling its vapors or causing any contact with the skin or clothing. Wear your protective glasses at all times. Use the extractors to work with these acids. A. Nitration of methyl benzoate 1. Preparation of the reactants. In the extractor you will find a burette with concentrated sulfuric acid, a second burette with concentrated nitric acid, clearly identified. Familiarize yourself with the scales of...

You have been given a sample rock (1.001 kilograms) that has Silver Carbonate throughout. The rock also has some inert material mixed in that will not affect your analysis. You decide that you want to retrieve the Silver (Ag) from the rock, so that is what we will do. 1) To make the Silver soluble, you need to dissolve it. To do this, you choose to use Nitric Acid. a. Write the balanced equation for the reaction of Silver Carbonate...
