Reversible reaction to consider: CO2(g) + H2O(l) + Na+(aq)+Cl-(aq)= HCO3(aq) +H+(aq)+Cl-(aq) Note: This reaction models atmospheric CO2 which dissolves in the ocean in a reversible reaction. Answer the following questions: 1. From an equilibrium perspective, what happens to the pH of the ocean when the concentration of CO2 in the atmosphere increases? 2. What affect on equilibrium would occur if some Na is removed from the reaction? 3. If the pH of the ocean was lowered by adding a large quantity...

(6 marks) An easy way to analyse the amount of CO2 in a gaseous mixture of CO2 and CO is to pass the gaseous mixture through an aqueous solution that contains excess Ba(OH)2. The CO2 will react yielding a precipitate of BaCOs but the CO does not react (you will learn why in higher classes). The aforementioned method was used to analyse the equilibrium composition of the gas evolved when 1.77 g of CO2 reacted with 2.0 g of graphite...
