Question

Q7.What happens when Zinc reacts with Copper Sulphate ? *
a) Zinc Sulphate and Copper
O b) No reaction
O c) Zinc Sulphate and hydrogen gas
O d) Zinc Sulphate and water​

Answer 1

Answer:

When zinc and copper sulphate react in the aqueous state, a simple displacement reaction will take place in which the zinc will displace the copper from the copper sulphate to form zinc sulphate. The colour of the solution will go from blue to colourless due to the change in the cation of the compound.

Answer 2

Explanation:

given::

zinc reacts with copper sulphate

to find::

observation

solution::

when zinc reacts with copper sulphate, a displacement reaction takes place.

empirical formula of zinc=

$\boxed{\underline{\underline{\red{\tt zinc = Z }}}}$

empirical formula of copper sulphate=

$\boxed{\underline{\underline{\red{\tt cuso^4 }}}}$

reaction that occured=

$\boxed{\underline{\underline{\blue{\tt Z + CuSO^4 = ZnSO^4 + Cu }}}}$

this reaction occured because,

reactivity series of zinc is higher than copper.

exchange if ions takes place which results in the formation of zinc sulphate ion and copper metal.

option (a) is the correct answer.
