Identifying the Metal that replaces magnesium from its salt:
Calcium (Ca):
- Calcium is the metal that can replace magnesium from its salt.
- This is because calcium is higher in the reactivity series than magnesium.
- In the reactivity series, metals are arranged in order of their reactivity, with the most reactive metals at the top and the least reactive at the bottom.
- Since calcium is above magnesium in the reactivity series, it has the ability to displace magnesium from its salt.
Explanation:
- When a more reactive metal comes into contact with the salt of a less reactive metal, a displacement reaction occurs.
- In this case, when calcium reacts with magnesium salt, calcium displaces magnesium from its salt.
- The displacement reaction can be represented by the following chemical equation:
Ca + MgSO4 → CaSO4 + Mg
- As a result of this displacement reaction, magnesium is replaced by calcium in the salt compound.
Conclusion:
- Therefore, the metal that replaces magnesium from its salt is calcium (Ca), due to its higher reactivity compared to magnesium.
