Question

what happens when an iron nail is immersed in copper sulphate solution? Give the relevant equation class 7.
the one who answers first I will make home the brainliest answer​

Answer 1

$\bf \bigstar$ Case (given) :

• An iron nail is immersed in an aqueous solution of copper sulphate.

$\bf \bigstar$ Reaction :

• As we know that an iron is more reactive than the aqueous copper(cuso4)sulphate solution. Therefore, the copper sulphate will turn in a pale(light) green in color. And, also the iron nail will have a brownish coating.

$\bf \bigstar$ Equation :

$\sf \blue{ cuso4} + \gray{Fe_2O_3•32H_2O} \to \green{feso4}$
