Q
Q: What is the pH of a 0.001 M solution of sodium bicarbonate (NaHCO3)?
Solution:
Sodium bicarbonate is a weak base. The pH can be estimated to be around 8.4 for a 0.001 M solution.
Steps: 5
Show Steps
Step 1: Understand that sodium bicarbonate (NaHCO3) is a weak base.
Step 2: Know that weak bases do not fully dissociate in water, meaning they do not release all their hydroxide ions (OH-).
Step 3: Recognize that the concentration of the sodium bicarbonate solution is 0.001 M.
Step 4: Use the approximate pH value for weak bases; for sodium bicarbonate, a 0.001 M solution typically has a pH around 8.4.
Step 5: Conclude that the pH of the 0.001 M sodium bicarbonate solution is approximately 8.4.
