Subject of the main interest was how the electrolysis parameters affect the duration of dendrites life. The selected set of parameters did provide a surprisingly regular dendrite’s life,<em> i.e.</em>, period from start of the electrolysis until dendrites detachment from the cathode. Dendrite’s growth did proceed with lowering of the zinc current efficiency, and the end of life was manifested by intensive hydrogen evolution due to corrosion of detached zinc deposit in the acid electrolyte. Current efficiency was successfully followed by the bubble counting technique, invented especially for kinetic studies of gas including reactions. The acquired results on dendrites’ life duration were so exact that it was easy to unify all five mono-variable dependencies into one five-variable expression. The calculated values of life duration did differ from the measured ones by only ±3 %! This is a proof that the developed expression accurately presents the real nature of dendritic growth under the applied con­ditions, <em>i.e.</em>, 0.5 to 2 M zinc (II) ions, 0.41 to 3.06 M H<sub>2</sub>SO<sub>4</sub>, 10 to 2500 mg dm<sup>-3</sup> copper (II) ions, 0.14 to 14 g dm<sup>-3</sup> hexamethylenetetramine, and 4.25 to 103 mA dm<sup>-2</sup> current density. The eventual broader region of Zn dendrites’ strict regular growth is not excluded.</p>}, number={9}, journal={Journal of the Serbian Chemical Society}, author={Gramatikov, Dimitar and Hadži Jordanov, Svetomir}, year={2022}, month={Jul.}, pages={1049–1062} }
