Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO3 and HI are mixed
To determine the ionic equation for the reaction between aqueous solutions of MgSO3 and HI, we need to first write the balanced molecular equation and then break it down into its constituent ions.
The molecular equation for the reaction can be written as:
MgSO3(aq) + 2 HI(aq) → H2SO3(aq) + MgI2(aq)
Now, let's separate the compounds into their respective ions:
MgSO3(aq) can be broken down into Mg2+(aq) and SO32-(aq)
HI(aq) can be broken down into H+(aq) and I-(aq)
H2SO3(aq) can be written as H+(aq) and SO32-(aq)
MgI2(aq) can be separated into Mg2+(aq) and 2 I-(aq)
The ionic equation will only include the ions that undergo a chemical change, while spectator ions (ions that don't undergo a chemical change) are excluded. In this case, the spectator ions are Mg2+(aq) and SO32-(aq).
Thus, the complete ionic equation for the reaction would be:
2 H+(aq) + 2 I-(aq) → H2SO3(aq) + 2 I-(aq)
Simplifying the equation and removing the spectator ions, we get:
2 H+(aq) + SO32-(aq) → H2SO3(aq)
So, the correct option is: 2 H+(aq) + SO32-(aq) → H2SO3(aq)
The complete ionic equation for the reaction between aqueous solutions of MgSO3 and HI is:
2 H+(aq) + SO32-(aq) + Mg2+(aq) + 2 I-(aq) → H2SO3(s) + MgI2(aq)
