Question

Cu SO4-> Su -> Cu (No3)2 -> Cu (OH) 2

Answer 1

CuSO4 + Mg — MgSO4 + Cu
Cu + 4HNO3 — Cu(NO3)2 + 2NO2 + 2H2O
Cu(NO3)2 + 2KOH — Cu(OH)2 + 2KNO3

Answer 2

The chemical equation you provided represents a series of chemical reactions involving copper sulfate (CuSO4), sulfuric acid (H2SO4), and copper nitrate (Cu(NO3)2), ultimately leading to the formation of copper hydroxide (Cu(OH)2). Let's break down the reactions step by step:

1. CuSO4 (copper sulfate) reacts with H2SO4 (sulfuric acid) to form sulfuric acid copper salt and water. Equation: CuSO4 + H2SO4 → Cu(HSO4)2 + H2O

2. Cu(HSO4)2 (copper hydrogen sulfate) decomposes into CuO (copper oxide), SO3 (sulfur trioxide), and water when heated. Equation: Cu(HSO4)2 → CuO + SO3 + H2O

3. CuO (copper oxide) reacts with H2SO4 (sulfuric acid) to form CuSO4 (copper sulfate) and water. Equation: CuO + H2SO4 → CuSO4 + H2O

4. CuSO4 (copper sulfate) reacts with H2O (water) to form Cu(H2O)62+ (hexaaquacopper(II) complex ion). Equation: CuSO4 + 6H2O → Cu(H2O)62+ + SO4^2-

5. Cu(H2O)62+ (hexaaquacopper(II) complex ion) reacts with NaOH (sodium hydroxide) to form Cu(OH)2 (copper hydroxide) and Na2SO4 (sodium sulfate). Equation: Cu(H2O)62+ + 2NaOH → Cu(OH)2 + 2Na+ + 6H2O

So, the overall chemical reaction sequence is: CuSO4 + H2SO4 → Cu(HSO4)2 + H2O Cu(HSO4)2 → CuO + SO3 + H2O CuO + H2SO4 → CuSO4 + H2O CuSO4 + 6H2O → Cu(H2O)62+ + SO4^2- Cu(H2O)62+ + 2NaOH → Cu(OH)2 + 2Na+ + 6H2O

In summary, starting with copper sulfate, the reactions produce copper hydroxide (Cu(OH)2) as one of the final products.
