Question

a substance X used for coating iron articles is added to a blue solution of a reddish brown metal why the colour of the solution fades away identify x and y and the type of the reaction involved​

Answer 1

Answer:

Well, the substance X Is zinc metal since it is used to galvanise iron metal to protect it from Rusting

Also, The blue solution of reddish brown metal is Copper Sulphate.

Now, when zinc is added to copper sulphate it displaces copper from it's Sulphate and forms zinc sulphate which is colourless and hence we say that the colour fades away and reddish brown deposit of copper metal sediments down.

I don't what y has asked as? So, but now you know what all is happening in this question's reactions ^_^

Hope this helps you !

Answer 2

Zinc is the metal used to coat iron in Galvanisation.

Blue solution is copper sulphate and the reddish brown metal is copper.

Explanation:

Blue colour fades because Zinc displaces copper from it’s salt because it’s more reactive than copper according to the reactivity series.
