The above equation represents the chemical reaction between Copper (II) Sulfate (CuSO4) and Potassium Cyanide (KCN) to produce Copper (II) Cyanide (Cu(CN)2) and Potassium Sulfate (K2SO4).
- Reaction Conditions
The standard conditions for this reaction to occur are a temperature of about 298K (25 degrees C) and a pressure of 1 atm. However, this reaction can occur at different temperatures and pressures.
- Reaction process
-
Stage 1: CuSO4 and KCN react with each other to produce Cu(CN)2 and K2SO4.
-
Stage 2: Cu(CN)2 and K2SO4 continue to react with each other to produce the final product.
This chemical reaction is a type of replacement reaction, where the Cu2+ ion of the CuSO4 compound is replaced by the CN- ion of the KCN compound.
- Phenomena observed
During the reaction process, you will see a color change in the solution. Initially, the solution is blue due to the presence of CuSO4. When KCN is added, the solution will turn colorless because Cu(CN)2 is colorless.
