Question- Could someone explain clearly why a solution of aniline in diluted HCl will not react with acetic anhydride unless sodium acetate is added?
I am not able to get the correct answer please help me
What volume of 1.40M NaOH solution must you add in order to prepare an acetate buffer of pH = 4.83? (The pKa of acetic acid is 4.76).
Equal volumes of 0.190 M weak base (Kb = 2.5× 10-9) and 0.190 M HCl are mixed. Calculate the pH of the resulting solution.
