(a) Explanation Given The pH of unpolluted rain is 5.4 . The concentration of carbon dioxide forty years ago is 315 ppm ( 315 × 10 − 6 g / L ) . Dissociation reaction of H 2 CO 3 is, H 2 CO 3 ( a q ) → H + ( a q ) + HCO 3 − ( a q ) The ICE table for the equilibrium concentration of the H 2 CO 3 , HCO 3 − , and H + is, H 2 CO 3 ( a q ) ⇌ H + ( a q ) + HCO 3 − ( a q ) Initial m 0 0 Change − x x M x M Equilibrium m − x x M x M The equilibrium constant ( K a ) is calculated by the formula, K a = Concentration of product concentration of reactant Substitute the value of concentration of product and concentration of reactant in the above equation, K a = [ H + ] [ HCO 3 − ] [ H 2 CO 3 ] The [ H + ] is calculate by the formula, pH = − log [ H + ] Substitute the value of pH in the above equation, 5 .4 = − log [ H + ] [ H + ] = antilog ( − 5.4 ) = 3.98 × 10 − 6 M The value of K a for H 2 CO 3 is 4.3 × 10 − 7 (refer to appendix D) Substitute the value of K a , H 2 CO 3 , H + , and HCO 3 − from ICE table in equation(1) , k a = ( x ) ( x ) ( m − x ) Substitute the value of K a , H 2 CO 3 , H + , and HCO 3 − in the above equation , 4.3 × 10 − 7 = ( 3.98 × 10 − 6 ) ( 3.98 × 10 − 6 ) ( m − 3.98 × 10 − 6 ) m = 4.08 × 10 − 5 M The value of m represents the concentration of the H 2 CO 3 . Therefore, the concentration of H 2 CO 3 is 4.08 × 10 − 5 M . The number of moles is calculated by the formula, Number of moles = Mass Molar mass Molar mass of carbon dioxide is, 12.007 + 2 × 15.999 = 44 (b) Interpretation Introduction To determine: The volume of CO 2 dissolved in 20 .0 L of water.
