How to find the oxidation number of cr(oh) 3

Answer 1

Step to calculate oxidation number for $Cr(OH)_3$

• Identify the oxidation number of each element present in the compound.
• Accordingly, the oxidation number of Cr is +3, H is +3, and O is (-2 × 3) -6.
• As the given compound is neutral, the sum of its all oxidation number will be equal to zero.
• When all the oxidation number of the compound is added, it gives

(+3) + (-2×3) + (+3)

6 + (-6)

6-6 = 0

• Thus the oxidation number for $Cr(OH)_3$ is calculated as 0, as it is a neutral compound.
