A chemistry teacher prepares a mixture by dissolving copper sulfate in water until the solution is clear blue. Why is this considered a homogeneous mixture?
The mixture appears as a single phase with no visible separation
When copper sulfate dissolves completely in water, the resulting solution has uniform composition throughout with no visible boundary between components, which is the defining feature of a homogeneous mixture. Hence, the mixture appearing as a single phase with no visible separation is correct.
