Farbveränderung durch Wasser?

ByHelene431

Gegeben ist: 84 g blaues Kupfer(Il)-sulfat-Pentahydrat werden ent-wässert. Dabei entstehen 53,7 g weißes wasserfreies Kupfer(Il)-sulfat daraus soll man den prozentualen Masse Anteil Wasser im Kupfer(Il)-sulfat-Pentahydrat berechnen. Rosafarbenes Cobalt(Il)-chlorid-Hexahydrat enthält 45,83 % Wasser. Wie kann ich das gut und einfach lösen? Danke schonmal fürs helfen

In the redox series, atoms are still ions, even no elements, but redox pairs. On the left the reduced, on the right the oxidized form.

You may know Cr -> Cr(III), but chrome also likes to be six-valued, so there is also the pair Cr(III) -> Cr(IV).

Maybe your new redox series is more for advanced people. Chromates are more interesting than the simple oxidation of metals that are known for the pleasure of Zink & Co.

You need to ask the author/editor what aspects/selection criteria the list was compiled.
