    What is the chemical equation for potassium oxide + water —> potassium hydroxide?

    ##”K”_2″O” + “H”_2″O” -> 2″KOH”##

    Potassium oxide + water produces potassium hydroxide.

    Potassium oxide is an ionic compound. The potassium has a charge of ##”K”^+## and oxygen has a charge of ##”O”^(2-)##. We need 2 potassium ions to balance one oxide ion making the formula ##”K”_2″O”##.

    Potassium hydroxide is an ionic compound. The potassium has a charge of ##”K”^+## and hydroxide has a charge of ##”OH”^-##. We need 1 potassium ion to balance one hydroxide ion making the formula ##”KOH”##.

    ##”K”_2″O” +” H”_2″O” -> “KOH”##

    To balance the equation we place a coefficient of 2 in front of the potassium hydroxide.

    ##”K”_2″O” + “H”_2″O” -> 2″KOH”##
