Question

What would the result be if the solution was not basic when it was heated to form CuO?

Some of the [Cu(H2O)6]2+ would not be converted to Cu(OH)2 and would remain in solution, causing a lower recovery Cu(s)

The [Cu(H2O)6]2+ solution would be directly converted back to Cu(s), in a one step reaction, causing a very high recovery of Cu(s)

Too much of the [Cu(H2O)6]2+ would be converted to CuO(s) causing an increased recovery Cu(s)

The acidity level of the solution is irrelevant

A

B

The [Cu(H2O)6]2+ solution would be directly converted back to Cu(s), in a one step reaction, causing a very high recovery of Cu(s)

C

Too much of the [Cu(H2O)6]2+ would be converted to CuO(s) causing an increased recovery Cu(s)

D

Explanation / Answer

The result obtained if the solution was not basic when it was heated to form CuO is -

A. Some of the [Cu(H2O)6]2+ would not be converted to Cu(OH)2 and would remain in solution, causing a lower recovery Cu(s)
