Copper I 和 Copper II 有咩唔同? 15点

Question

如题所述

Answer 1

Copper(I) me Cu+ ion or the pound containing Cu+ ion. Copper(II) me Cu2+ ion or the pound containing Cu2+ ion. Copper(II) pounds
e.g. copper(II) sulphate crystals and copper(II) oxide
are monly used in laboratory. In aqueous solutions
copper(II) is blue in colour. Copper(I) pounds are less mon. This is because copper(I) cannot exist in aqueous solution. In aqueous solution
copper(I) ion undergoes disproportionation (self redox) to give copper metal and copper(II) ion. 2Cu+(aq) → Cu2+(aq) + Cu(s) Cu(I) only exists as insoluble solids (e.g. copper(I) oxide
Cu2O) or plex (e.g. [CuCl2]-).
就好似 Fe2+ 同 Fe3+ 有咩唔同??? 佢地既唔同系在于copper II已经去到最尽
佢既oxidizing number 已经去到冇得再去
姐系+2
所以佢系冇得再被氧化..但Copper I就唔同
佢可以再继续被oxidizing 既野好似mno4- 甘去oxidized
