Answer #1

pH of the sodium bicarbonte will not change because it has some buffering capacity. Buffering capacity means which resists to change the pH of the solution.

When Sodium carbonate dissolves in water it become basic. The Chemical equation will be

Na2CO3 + H2O---> NaOH [strong Base]+H2CO3 [Weak Acid] Since the products contains both acid base the resulted solution will not be neutral, Soultion will be still alkaline beacuse of the preseance of strong base [NaOH]

An experiment was to identify the unknown solution as sodium carbonate or sodium bicarbonate by reacting it with HCl and taking pressure measurements. My chemical equations are: NaHCO3+HCl--->CO2+H2O+NaCl Na2CO3+2HCl--->CO2+H2O+2NaCl. The instructor said that it can be determined by looking at the chemical equation. My response was the pressure measurements were from the unknown were closer to sodium bicarbonate than sodium carbonate. Is this a correct assumption?
