2M of 100 ml Na2 SO4 is mixed with 3M of 100 ml NaCl solution and 1M of 200 ml CaCl2 solution. Then the ratio of the concentration of cation and anion.

A

½

B

2

C

1.5

D

1

Answer

1

Explanation

Solution

(4)

Conc. of cation =400+300+200400= \frac{400 + 300 + 200}{400}

conc. of anion =200+300+400400= \frac{200 + 300 + 400}{400}

∴\therefore ratio of the conc. = 1
