WitrynaCu>Hg>Au>Ag. Thus, When silver (Ag) metal is added to copper sulfate (CuSO 4) solution, no reaction takes place as silver is less reactive than copper so it can not displace copper from its solution. Ag+CuSO 4→ no reaction. Solve any question of Metals and Non metals with:-. Patterns of problems. Witryna4 sie 2024 · The Trio of Unreactive Metals. And the least reactive metals we need to know are copper, silver, and gold. The trio sit in the same column within the transition … WitrynaReactivity series. In CACA, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest. [2] [3] It is used to summarize information about the reactions of metals with acids and water, single displacement reactions ... kitchen projector
