The pH of the resultant solution of 20 ml of 0.1 M H_3PO_4 and 20 ml 0

1.	The pH of the resultant solution of 20 ml of 0.1 M H_3PO_4 and 20 ml 0.1 M Na_3PO_4is
Answer» ` pK_(A1) +log 2 ` ` pK_(al) ` ` pK_(a_2)` `(pK_(a1)+pK_(a_2))/(2)` SOLUTION :` {:( H_3PO_4 +, PO_4^(-3)HARR, H_2PO_4^(-), +HPO_4^(-2) ),( 2 meq , 2meq ,0,0) :}` ` pH =P^(Ka_2) +log ""(2)/(2), pH =p^(Ka_2)`
