CuO + H2SO4

will effervescence occur when copper (II) oxide heated with sulphuric acid??

CuO + H2SO4 => CuSO4 + H2

effervescence means any gaseous product form after the reaction?

effervescence means any gaseous product form after the reaction? should be yes

but equation should be CuO + H2SO4 => CuSO4 + H2O

so no effervescence

You should remember that CuO is alkali:D :D :D

Effervescene其實係要大量gss同時evolve
中文叫泡騰現象呢

回覆3 #的帖子

應該係base
Alkali係溶得係水的base

..
Bases 分為alkalis同bases

effervescence will not occur as H2O is produced
