Logan is cooking, and he wants to increase the boiling point of the water. which solute would not be a good choice as it would not increase the boiling point as much as the others? a. salt, nacl b. magnesium sulfate, mgso4 c. potassium sulfate, k2so4 d. sucrose, c12h22o11

Sugar would not increase the boiling point of the water as much as the others.To show this, we recall the equation for boiling point elevation ∆t:  
     ∆t = i Kb m 

The difference in these four solutions will be in the product of the van't Hoff Factor i and molality m: i * m. 

If we assume that we have 0.1m of each solute, the products i*m for these solutions are:
     
     Solution                      Identity of particles                          i      i * m
        0.1 m NaCl                 Na+, Cl-                                         2     2 * 0.1 = 0.2
        0.1 m MgSO4             Mg^2+, SO4^2-                            2     2 * 0.1 = 0.2
        0.1 m K2SO4              two K+, SO4^2-                           3     3 * 0.1 = 0.3
        0.1 m C12H22O11      covalently bonded molecules     1     1 * 0.1 = 0.1

Therefore, having the lowest  i * m, sucrose will have the lowest boiling point elevation.
