The values of van't Hoff factors for KCl, NaCl and `K_2SO_4` , respectively , are ___

Options

A. 2,2 and 2
B. 2,2 and 3
C. 1,1 and 2
D. 1,1 and 1

Answer

B

Explanation

Number of total ions present in the silution is known as van't Hoff factors (i).
`{:("Substanes","van't Hoff factor (i)"),("For"KCl," "2),("For"NaCl," "2),("For"K_(2)SO_(4)," "3):}`
Hence, correct choice is (b).
