Question

2. Toluene (C7Hs) is a component of gasoline and it is contaminating a water body due to a leaky storage tank. The concentration in water of the toluene is 4.25ppm. The starting pH of the water is 3.0 and this is a completely un-buffered system (i.e protons that are liberated remain in solution and protons that are consumed are lost from solution during the RXNs taking place). Fe(OH)3 is present and will serve as an electron acceptor for toluene oxidation; it is reduced to Fe2. Toluene is oxidized to 3mol acetate (C2H302) and 1mol CO2. How many mol protons are liberated/consumed in this reaction, and assuming no buffer, will the pH increase or decrease)?
