Question 1 • PF 2425 NW3 Chemistry CR

Which compounds will most likely dissociate when dissolved in water? Select all that apply.

Answer
A
barium hydroxide (Ba(OH)2)
B
ethanol (C2H6O)
C
glucose (C6H12O6)
D
silver nitrate (AgNO3)
E
dichloromethane (CH2Cl2)
F
potassium chloride (KCl)

Explanation

Compounds that dissociate in water are typically soluble ionic compounds, which separate into their ions. Barium hydroxide, Ba(OH)₂, separates into Ba²⁺ and OH⁻ ions; silver nitrate, AgNO₃, into Ag⁺ and NO₃⁻; and potassium chloride, KCl, into K⁺ and Cl⁻. Ethanol and glucose are molecular compounds that dissolve without separating into ions, while dichloromethane does not dissociate into ions in water.
