A decimolar solution of potassium ferroc...

A decimolar solution of potassium ferrocyanide `K_4Fe(CN)_6` is 50% dissociated at 300 K. Calculate the value of van't Hoff factor for potassium ferrocyanide.

Text Solution

Verified by Experts

`alpha = 50% = 0.50`
`i= 1+ 2 alpha`
`= 1 + (2 xx 0.50) = 1 + 1 = 2 `
