PH and pOH Formulas
Concentration Formulas
pH = -log[H30)
[H30*) = 10-PH
pOH = -log(OH)
[OH] = 10-POH
pH + POH = 14.00
[H3O+][0] = 1.0 10-14
What is the hydronium (H30*) concentration of a solution with a pH of 3.60?
A 2.5 x 10^M
B 3.0 x 10-M
C 4.0 x 10M
D.
45* 10-11M

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
