1. Hydrogen 係正定負?
HCl (aq) ----------------> H+ (aq) + Cl-(aq)
咁H 係+
但H2O 係covalent compound ........咁H 味負lor
HCl都係covalent compound H 都係負
咁幾時Hydrogen 係正 幾時係負??
我上面問ge野可能會唔岩,,請多多指教~~~~~
Plz 解釋俾我聽~in ce 角度 唔該哂~~~~~~
2. NH4Cl + NaOH ------------> NH3+ +H2O + NaCl
呢個我明
但如果只係得NH4 而唔係NH4Cl 咁仲有冇可能會有reaction??
仲有單一一個NH4 而唔係NH4 compound 會唔會有反應??
請解釋~同埋寫埋Full and ionic equation~~plz
