Solubility
Which of the following are nonelectrolytes? *
Pentacarbon decahydride (C5H10)
O
Magnesium chloride (MgCl2)
O
Copper phosphate (Cu3(PO4)2]
Sulfur trioxide (SO3)
O
0
Aluminum oxide (A1203)
Phosphorus pentachloride (PC15)
Glucose (C6H1206)

Non electrolytes are Pentacarbon decahydride, Phosphorus pentachloride, Glucose.

Explanation:

Non electrolytes do not exist as ions in aqueous solution. Since it does not get dissociated into ions, these non electrolytes do not conduct electricity when it is dissolved or it is heated or melted.

Pentacarbon decahydride is a non electrolyte.

Magnesium chloride is an electrolyte.

Copper phosphate is an electrolyte

Sulfur trioxide is an electrolyte.

Aluminum oxide is an electrolyte

Phosphorus pentachloride do not get dissociated into its ions so it is a non-electrolyte.

Glucose gets dissolved in water but do not dissociate into ions, so it is a non electrolyte.
