multiple choice 1 point which observations confirm that separation and purification were successful? all compounds dissolve in water after recovery ether evaporates completely without residue no precipitate forms in any step distinct melting points close to literature values for each compound

Answer

Answer:

Distinct melting points close to literature values for each compound

Brief Explanation:

Melting - point is a characteristic property of pure substances. Distinct melting points close to literature values indicate high purity of separated compounds, confirming successful separation and purification. Other options do not directly prove purity and successful separation.
