Question

If degree of ionisation of ki3 is 80percent then what will be the can't Hoff factor

Answer 1

Well it's my first answer in brainly and you are lucky to be the first one who got my help....jokes aside

KI3 ionises like K+ and 3I-

So, no. of ions, n=3+1=4

Now for dissociation we have,

α= i-1/n-1

Or. 0.8 = i-1/4-1

Or, 0.8*3 = i-1

Or, i-1 = 2.4

So, vant Hoff factor(not cant Hoff),

i = 2.4+1 = 3.4

It's as easy as that...keep rocking chemistry
