Question
Calculate the pH of solutions having these $\mathrm{H}^{+}$ion concentrations:(a) 0.01 M(b) 1.0 M(c) $6.5 \times 10^{-9} \mathrm{M}$
Step 1
The pH of a solution is calculated using the formula: \[ \text{pH} = -\log[\mathrm{H}^+] \] where \([\mathrm{H}^+]\) is the concentration of hydrogen ions in moles per liter (M). Show more…
