Question

i am calculating valancy of cu in cuso4 it is coming +10. Anyone pls help me to solve this​

Answer 1

Answer:

Valency of Cu is +2

Explanation:

$valency \: of \: SO _4 \\ is \\ \\ valency \: of \: S \: = + 6 \\ \\ valency \: of \: O \: = - 2 \\ \\ overall \: valency \: of \: SO _4 \\ \\ = + 6 + 4( - 2) \\ \\ = 6 - 8 \\ \\ = - 2 \\ \\ valency \: of \: SO _4 = - 2$

Therefore now the valency of Cu in CuSO4 is +2

• Note:Valency of Sulphur varies from -2 to +6 depending on its constituents
