Question

C3H8O3 - glycerol Major species present when dissolved in water

Answer 1

Answer:

$\rm C_{3}H_{8}O_{3}(aq)$

Explanation:

Glycerol is a covalent molecule. The major species in an aqueous solution will be hydrated glycerol molecules.

$\rm C_{3}H_{8}O_{3}(l) \longrightarrow \, C_{3}H_{8}O_{3}(aq)$

Answer 2

Answer: Water and glycerol are the major species that are present when dissolved in water.

Explanation:

Glycerol is a covalent compound because it is formed by the sharing of electrons between carbon, oxygen and hydrogen atoms.

Covalent compounds when dissolved in water behave as non-electrolytes.

Non-electrolytes are defined as the species which does not get dissociated into its ions when dissolved in water.

Thus, when glycerol is dissolved in water, the major species which must be present in the solution are water and glycerol itself.
