How can I prepare 30m ZnCl2 aqueous solution?

12 June 2024 1 4K Report

A 30m ZnCl2 aqueous solution is needed to prepare and use the electrolyte, as used in some references denoted below.

[Liang, Guojin, et al. Nature Communications 14.1 (2023): 1856.]

Despite several attempts, undissolved ZnCl2 salt remains visible. I aim to use electrolytes that are fully dissolved at room temperature.

30m ZnCl2 can dissolve in water, depending on the salt brands. Sigma Aldrich 98% / Alfa Aesar 99.95% is OK, while Wako 99.9% can not reach 30m.
