Question
Sodium and potassium due to their high reactivity are kept in:
- Kerosene oil
- Water
- Alcohol
- Diesel
Hint:
Kerosene oil
The correct answer is: Kerosene oil
Sodium and potassium are very reactive metals and kept in kerosene oil to prevent it from coming in contact with oxygen and moisture as they react to form their hydroxides. This is an exothermic reaction and lot of heat is generated so both the metals are kept in kerosene oil.
