changes in the pH of a solution (5 points) 2. Cooks use baking soda to make cakes light and fluffy. You might have used baking soda yourself. Baking soda is NaHCO3. A 0.1 M solution of baking soda in water has a [H+] of about 4.0 × 10–9. (You may prefer to think of the hydronium ion concentration‚ [H3O+]‚ as 4.0 × 10–9.) Write the formula for the calculation of pH‚ and then show each step as you calculate the pH of a 0.1 M solution of baking soda. Answer: pH = -log [H⁺] ←←[log without a specified
