Titration curves for 0.1M solution of three weak acids HA_1,HA_2 and H

1.	Titration curves for 0.1M solution of three weak acids HA_1,HA_2 and HA_3 with ionization constants K_1, K_2 and K_3 respectivelyare plotted as shown in the figure. Which of the following is/are true?(##AKS_ELT_AO_CHE_XI_V01_B_C05_E02_135_Q01.png" width="80%">
Answer» `K_2 =(K_1+K_3) //2` ` K_1 lt K_3` ` K_1 gt K_2` ` K_2 gt K_3` SOLUTION :` 2 lt 4 lt 5 rArr K_1 gt K_2 gt K_3` ACID strength ` ALPHA (1)/( pH)`
