Question

What is the value of vant hoff factor in co(no3)2?

Answer 1

Answer:

3

Explanation:

vant hoff factor is represented by i

we should know the formula

i=1+(n-1)α   to solve this problem

where,

n=no of ions dissociated in the solution

α=degree of disassociation

let α=1 since its not mentioned in the question

Co(NO₃)₂----------> Co⁺ + 2NO₃²⁻

no of molecules/atoms=n

n=1+2

=3

therefore plugging in the values in the formula

i=1+(n-1)α

i=1+(3-1)1

=3

therefore the Vant Hoff factor is 3

Hope this helps
