For example copper chloride will produce a blue flame.

The green color is often attributed to oxidized copper compounds, such as copper chloride.

Treatment with sodium sesquicarbonate removes copper chlorides from the corroded layer.

Should I order the copper chloride or make a change to the procedure to get a better yield with copper sulfate?

Further complicating the Wacker process mechanism is questions about the role of copper chloride in the mechanism.

It can be made by heating copper(II) chloride very hot.

The Deacon process takes place at about 400 to 450 C in the presence of a copper chloride:

The usual test for the presence of lead in a reaction solution is to add copper chloride.

Our chemistry teacher was out of copper chloride, so instead, our class period used copper sulfate.

In the latter method, a solution of copper chloride and the test solution is allowed to evaporate.
