The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in
aqueous solutions. The definiton of pH is in terms of base 10 logarithms.
pH = -log[H+]
where (H+) is the hydrogen ion concentration.
a. If the hydrogen ion concentration in a solution is 8.89 x 10-3 mol/L, the pH is
b. If the pH of a solution is 3.332, the hydrogen ion concentration is
mol/L.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
