Explanation:
CO2 reacts with water to form carbonic acid as follows;
CO2(g) + H2O(l) ---------> H2CO3(aq)
This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.
Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.
Hello!
To solve this problem we need to know the value of
pKa for HC₂H₃O₂ (Acetic Acid) which is
4,76. Now we can apply the
Henderson-Hasselbach equation, as follows (assuming that HC₂H₃O₂ concentration is 0,22M):
So, the pH for this buffer solution of HC₂H₃O₂ and KC₂H₃O₂ is
4,50Have a nice day!
Answer is convalent . When electrons are shared, this is a convalent bond. Now if the electrons are transferred and not shared, this is an ionic bond. Ionic bonds are stronger than convalent bonds.
