Question

Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO3 and HI are mixed.

Answer 1

Answer: The complete ionic equation is written below.

Step-by-step explanation:

Complete ionic equation is defined as the equation in which chemical species are written in the form of ions. All the spectator ions are present in this equation.

The chemical equation for the reaction of magnesium sulfite and hydrogen iodide follows:

`MgSO_3(aq.)+2HI(aq.)\rightarrow MgI_2(s)+SO_2(g)+H_2O(l)`

Complete ionic equation for the above reaction follows:

`Mg^(2+)(aq.)+SO_3^(2-)(aq.)+2H^+(aq.)+2I^-(aq.)\rightarrow MgI_2(s)+SO_2(g)+H_2O(l)`

Hence, the complete ionic equation is written above.

Answer 2

we are asked to give the equation of the raction of aqueous solutions of MgSO3 and HI. In this case,the type of reaction involving these two reactants is double replacement or substitution where the places of the cations are exchanged in the products side. The equation thus is expressed:
MgSO3(aq) + 2HI(aq) → MgI2(aq) + SO2(g) + H2O(l)
