Question

REENA IMMERSED A ZINC PLATE IN AN AQUEOUS SOLUTION OF COPPER SULPHATE . SHE NOTICED A THICK LAYER OF COPPER ON THE SURFACE OF THE ZINC PLATE AFTER HALF AN HOUR

*based on the above reaction . answer the following questions given below
1} What is the formula of the colourless solution formed after the reaction ?
2} What should Reena Have done to make the reaction faster ?
3} No reaction takes place when a copper plate is immersed in an aqueous solution of zinc sulphate. Explain the reason behind this ? { if anyone can answer this question with correct explanation ]

Answer 1

1. Zn + CuSO4 --> ZnSO4 + Cu

2. Added catalyst zinc, though the zinc in the metal plate already does it's part

3. Reactivity to Copper is less than Zinc and that's why the reaction rate is extremely slow to appear as no reaction. You can look up the reactivity series. It shows that Copper is way lower in order than Zinc. Because of high reactivity Zinc performs reaction with Copper. But due to lower reactivity than Zinc, Copper plate cannot dissipate as fast as Zinc and conduct a standard reaction
