Question

What is the oxidation state of each element in Mn(NO₃)₂?

A) Chemical oxidation analysis
B) Chemical formula oxidation evaluation
C) Ionic compound oxidation assessment
D) Chemical reaction redox evaluation

Answer 1

The oxidation state of Mn in Mn(NO₃)₂ is +2.

Step-by-step explanation:

The oxidation state of Mn in Mn(NO₃)₂ can be determined by assigning oxidation states to the other elements and applying the rule that the sum of the oxidation states in a compound must equal the compound's charge. In this case, the nitrate ion (NO₃) has a charge of -1, so the sum of the oxidation states of the two nitrate ions is -2. Therefore, the oxidation state of Mn must be +2 to balance out the charge.

So, the oxidation state of Mn in Mn(NO₃)₂ is +2.
