Morphology of copper electrodeposited from acid copper sulfate bath with Cl- ions on copper (110) face

The morphology of Cu electrodeposited on the 110 plane of Cu single crystals in highly purified solns. of CuSO4 and HCl was not affected by HCl <10-​4 moles​/l., but the deposition was facilitated. At higher concns., CuCl codeposited with Cu to produce a polycryst. product.
