How many moles of `Fe^(2+)` ions are formed when excess iron is treated with 500 mL of `0.4 N HCI` under inert atmosphere? Assume no change in volume

A

0.4

B

0.1

C

0.2

D

0.8

Text Solution

Verified by Experts

The correct Answer is:
B
`Fe+2HClrarrFeCl_(2)+H_(2)`
`"Moles of Fe"^(2)+"Formed"=(1)/(2)xx"Moles of HCl used"`
`=(1)/(2)xx(0.4xx500)/(1000)=0.1`
