我ar sir話calcium carbonate+hydrochloric acid=calcium chloride+carbon dioxide +water / calcium carbonate (heat)= calcium oxide+carbon dioxide
佢話hydrodencarbonate都可以產生carbon dioxide through acid and heating
咁 calcium hydrogencarbonate(heat)=calcium oxide+carbon dioxide+hydrogen 和 calcium hydrogencarbonate+hydrochloric acid=calcium chloride+carbon dioxide+water+hydrogen係咪正確??
我想問hydrogencarbonate和carbonate有咩關聯?

✔ 最佳答案
hydrogencarbonate和carbonate同野react的特性差唔多,不過通常hydrogencarbonate可溶係水, 但carbonate就唔溶係水,
同埋hydrogencarbonate ion係1負, 而carbonate ion係2負
條式唔正確,
應該係calcium hydrogencarbonate+hydrochloric acid=calcium chloride+carbon dioxide+water(冇hydrogen)

答錯野...hydrogencarbonate 係一定溶水, 唔係通常!

基本上carbonate和hydrogencarbonate的reactions都是一樣的
我的意思係話reaction with acid
我的意思係話reaction with acid
