Question
What is the pH of $0.15 \mathrm{M}$ acetic acid to which $1.56 \mathrm{g}$ of sodium acetate, $\mathrm{NaCH}_{3} \mathrm{CO}_{2},$ has been added?
Step 1
Acetic acid: Given concentration = 0.15 M Assuming volume = 1 L (since we need the ratio of moles) Moles of acetic acid = concentration × volume = 0.15 mol Sodium acetate: Given mass = 1.56 g Molar mass of sodium acetate = 22.99 (Na) + 12.01 (C) + 3 × 1.01 (H) Show more…
