In MgCl2, the oxidation state of 'Cl' is :
Correct answer: D. -1
- A. 0
- B. +2
- C. -2
- D. -1
Explanation
In MgCl2, the oxidation state of Mg is +2 since it is a Group 2 element and tends to lose two electrons to attain a noble gas configuration. Since MgCl2 is a neutral compound, the sum of the oxidation states of all the atoms in the compound should be zero.Let the oxidation state of Cl be x. Since there are two Cl atoms, the total contribution of Cl to the oxidation state will be 2x. Therefore, we can write:+2 + 2x = 0Solving for x, we get:x = -1Thus, the oxidation state of Cl in MgCl2 is -1.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
