Question
Which of the following oxides is soluble in water?
Solution
Explanation: Calcium oxide (CaO), also known as quicklime, readily reacts with water to form calcium hydroxide, Ca(OH)₂. This reaction is exothermic and results in a basic solution. FeO (iron(II) oxide) and ZnO (zinc oxide) are both relatively insoluble in water. They may react slightly with water, but they don't dissolve significantly under normal conditions.
