Question

Which of the following has the greatest effect on colligative properties?

A. Calcium chloride (CaCl2)
B. Sodium chloride (NaCl)
C. Aluminum Nitrate (Al(NO3)3)
D. Epsom salt (MgSO4)

Answer 1

aluminum nitrate (Al(NO3)3)

it has the greatest effect on collimation properties .

Step-by-step explanation:

(c) is correct option

Answer 2

C. Aluminum Nitrate (Al(NO3)3)

Step-by-step explanation:

This is because, when Aluminium nitrate dissolves in water, it dissociates to form four ions ( one aluminium ion and three nitrate ions ). Since colligative property depends on number of particles or ions present ( roult's law ), this will create much effect.

`Al(NO _(3) )_(3(aq)) → Al {}^(3 + ) _((aq)) + 3NO {}^( - ) _((aq))`
