Question

Explain what happens, on a molecular or ionic level, to the following when they dissolve in water:

a) glucose, C6H12O6

b) sodium chloride, NaCl

c) sodium sulfate, Na2SO4

Answer 1

a)

glucose won't form ions, it will remain as a 1 molecule only. The hydrophilic part of glucose will make it able to solubilize in water

b)

NaCl --> Na+ and Cl-

will split in ions, since it is a very good electrolyte; those are ionic substatntes

many properties will account as twice concnetration since there are now, same mol ions of Na+ and mol ionf o fCl-

c)

similar to "B"

NA2SO4 = 2Na+ + SO4-2

total ion = 3

will increase the interactions in water, since it is a very good electrolyte
