Answer: From the given options, Sodium oxide is soluble in water.
Explanation:
- Due to their low basicity, hard metal or transition metal oxides such as those of copper, zinc, iron, and chromium do not dissolve in water.
- Alkaline earth metal oxides also produce hydroxides in water, however these hydroxides only produce partially soluble solutions.
- Different metals react differently with water; some even have no reaction. Similar to how sodium and potassium react violently with water, they react violently and in a highly exothermic manner with cold water. Calcium has a less strong effect. Magnesium, on the other hand, reacts with hot water.
- Metals like aluminum, iron, and zinc react with steam to produce metal oxide and hydrogen gas instead of cold or hot water. Lead, copper, silver, and gold are just a few of the metals that don't even react with water.
- Metals can therefore be grouped in decreasing order of activity based on their metal reactivity. A reactivity series has been constructed based on displacement reactions of metals with other metal salts.
- Metals vary in their degree of reactivity; some are extremely reactive, some are moderately reactive, and some are least reactive.
