Question

Draw the graphic from Figure 15.12. Explain how it helps you calculate any of the values of
[H3 O+ ], [OH- ], pH, pOH once the value of any one of them is kno

Figure 15.12 summarizes the ways we can interconvert [H*], [OH-], pH, and pOH. The diagram may leave you wondering which path to follow to make conversions, such as [OH-] to pH. Two equivalent sets of calculations are shown: (i) [OH-] → pOH → pH or (ii) [OH¯] → [H₂O¹] → pH. Using either results in the same answer. pH pH = -log[H3O+] or [H3O+] = 10¯pH [H3O+] ← pH = 14.00 – pOH pOH = 14.00 - pH Kw=1.00 × 10-1 - 14 pOH = pOH = -log[OH-] or [OH-] = 10-POH [H3O+][OH-] FIGURE 15.12 Pathways for interconverting [H₂O*], [OH-], pH, and pOH values. → [OH-]
