Test your knowledge of pH / pOH calculations!
For the questions bellow, remember the following formulas to calculate pH, pOH, H+ and OH- values:
pH = 14 - pOH
pOH = 14 - pH
pH = -log (H+)
pOH = -log (OH-)
[H+] = 2nd log (-pH)
[OH-] = 2nd log (-pOH)
pH = 14 - pOH
pOH = 14 - pH
pH = -log (H+)
pOH = -log (OH-)
[H+] = 2nd log (-pH)
[OH-] = 2nd log (-pOH)
