25. 0 mL of 0. 050 M Ba (NO 3 ) 2 is mixed with 25. 0 mL of 0. 020 M NaF. K sp of BaF 2 is 0.5 x 10 -6 at 298K. The ratio of [Ba 2+ ] [F - ] 2 and K sp is
Text Solution
Verified by ExpertsThe correct answer is:
5
(5) Given:
Volume of Ba(NO 3 ) 2 solution = 25.0mL Concentration of Ba(NO 3 ) 2 solution = 0.050M Volume of NaF solution = 25. 0 mL Concentration of NaF solution =0. 020M
[Ba +2 ] = 
=0.025M
[Ba +2 ] [F - ]= 25 x 10 -7 K sp = 0.5 x 10
-6 = 5 x 10 -7
