What is the pH of a 0.1 M solution of sodium bicarbonate (NaHCO3)? (2022) 2022

Step 1: Understand that sodium bicarbonate (NaHCO3) is a compound that can act as a weak base in water.
Step 2: Recognize that when NaHCO3 dissolves in water, it produces bicarbonate ions (HCO3-).
Step 3: Know that bicarbonate ions can accept protons (H+) from water, which makes the solution slightly basic.
Step 4: Use the concentration of the solution (0.1 M) to estimate the pH. A 0.1 M solution of a weak base like NaHCO3 typically has a pH around 8.00.
Step 5: Conclude that the pH of the 0.1 M sodium bicarbonate solution is approximately 8.00.
