Question
Calculate the pH of(a) orange juice, $3.7 \times 10^{-4} \mathrm{MH}^{+}$(b) vinegar, $2.8 \times 10^{-3} \mathrm{M} \mathrm{H}^{+}$
Step 1
The pH is calculated using the formula: \[ \text{pH} = -\log[\text{H}^+] \] where \([\text{H}^+]\) is the concentration of hydrogen ions in moles per liter (M). Show more…

(a) The $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right]$ of an acidic solution is $3.5 \times 10^{-3} \mathrm{M}$. What is its pH? (b) The pH of tomato juice is $4.1 .$ What is its $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right] ?$ Is this solution acidic, basic, or neutral?
Finding pH The hydrogen ion concentration of a sample of each substance is given. Calculate the pH of the substance. (a) Lemon juice: $\left[\mathrm{H}^{+}\right]=5.0 \times 10^{-3} \mathrm{M}$ (b) Tomato juice: $\left[\mathrm{H}^{+}\right]=3.2 \times 10^{-4} \mathrm{M}$ (c) Seawater: $\left[\mathrm{H}^{+}\right]=5.0 \times 10^{-9} \mathrm{M}$
