Question
Which of the following reaction produces a base?
Answer: Option B
:
B
- Metal oxides react with water to form bases by associating with hydroxyl ion present in water. For example, the chemical reaction between calcium oxide and water:
CaO(s)+H2O(l)→Ca(OH)2(aq)
- Basic oxides can be made by the direct combination of metals with oxygen.
- Heating of metal carbonates produces metal oxide and releases CO2 gas.
- Salt and water are formed when acid reacts with base.
