Question

Van't Hoff factor of caco3 to is

Answer 1

Explanation:

Calcium nitrate on dissociation gives 2 moles of nitrate ions and one mole of calcium ions so the total number of moles of ions is 2+1=3.0

Answer 2

Answer:

calcium carbonate on dissociation gives :

CaCO3 = Ca²+ + CO3²-

total number of ion = 4

van't Hoff factor is = 4/1 = 4
