Titration curves for 0.10 M solution of three weak acids HX, HY and HZ

1.	Titration curves for 0.10 M solution of three weak acids HX, HY and HZ with ionization constants H_(1), K_(2) and K_(3) respectively are plotted as shown in the figure below:
Answer» `K_(2) = (K_(1) + K_(2))/(2)` `K_(1) lt K_(3)` `K_(1) GT K_(2)` `K_(2) gt K_(3)` Solution :N//A
