What is ionic equation?? |
| Answer» An equation which shows only the atoms and ions that actually take part is called an ionic equation. Such ions which remain as such and do not take part in the reaction are not indicated.When zinc metal and dilute sulphuric acid are reacted, then zinc sulphate and hydrogen gas are formed. Now sulphuric acid exists as 2H+ ion and SO-24 ions. Similarly, zinc sulphate exists as Zn2+ ions and SO-24 ions. So, the above reaction can be written as:Zn + 2H+ + S02-4 →Zn2+ + SO2-4 + H2 | |
