HCl + CuSO4 - Chemistry Forum
Mar 23, 2011 · HCl solution may react very slow with aluminum because of this protecting layer. Copper sulfate may not react at all for the very same reason but combination of copper salt and HCl create conditions when copper precipitates on the surface of aluminum and prevents formation of a dense Al 2 O 3 therefore creating conditions for even faster ...

Formation Mechanism for Zr2S - Chemistry Forum
Feb 21, 2025 · ZrOCl₂·8H₂O undergoes hydrolysis in water to form zirconium hydroxide (Zr(OH)₄) and hydrochloric acid (HCl): ZrOCl 2 ⋅8H 2 O→Zr(OH) 4 +2HCl+7H 2 O. Decomposition of Thiourea: Thiourea decomposes upon heating to release hydrogen sulfide (H₂S), which acts as the sulfur source for zirconium sulfide formation: CH 4 N 2 S→H 2 S+HCN+NH 3
