APFIVE Characteristics of an Endothermic Process
In what way does the dissolution of anhydrous copper sulfate (CuSO4) in water demonstrate the principles of an endothermic reaction?
A
The solution temperature decreases as CuSO4 dissolves, indicating heat absorption from the surroundings.
B
The solution turns blue due to Cu²⁺ ions, which is a characteristic of all endothermic processes.
C
The entropy of the system decreases, which is a defining feature of endothermic reactions.
D
The dissolution releases heat, causing the surrounding water to warm up significantly.
