write the phases for the following equation
Sr(NO3)2+2KIO3+H2O----->
Sr(IO3)2*H2O+2KNO3
and also write the net ionic equation
To write the phases for the given chemical equation, we need to know the state (phase) of each compound. However, the phase is not provided in this question. Usually, chemical equations use the following abbreviations to represent phases:
- (s) for solids
- (l) for liquids
- (g) for gases
- (aq) for aqueous solutions (dissolved in water)
So, to write the phases for the given equation, we need to assume the state of each compound. Here is a possible representation:
Sr(NO3)2(aq) + 2KIO3(aq) + H2O(l) → Sr(IO3)2•H2O(s) + 2KNO3(aq)
Please note that without specific information about the phases, these are assumptions I made based on the typical behavior of these compounds.
Now, let's write the net ionic equation. The net ionic equation represents only the species that are directly involved in the reaction. To obtain a net ionic equation, we need to separate the soluble ionic compounds into their constituent ions and omit the spectator ions (ions that appear on both sides of the equation unchanged).
The given equation is balanced, so the next step is to write the dissociation of the soluble compounds:
Sr(NO3)2(aq) → Sr^2+(aq) + 2NO3^-(aq)
KIO3(aq) → K+(aq) + IO3^-(aq)
H2O(l) → H2O(l)
Sr(IO3)2•H2O(s) → Sr^2+(aq) + 2IO3^-(aq) + H2O(s)
2KNO3(aq) → 2K+(aq) + 2NO3^-(aq)
Now, we can write the net ionic equation by canceling out the spectator ions:
Sr(NO3)2(aq) + 2KIO3(aq) + H2O(l) → Sr(IO3)2•H2O(s) + 2KNO3(aq)
Net Ionic Equation:
Sr^2+(aq) + 2IO3^-(aq) → Sr(IO3)2•H2O(s)
Please note that this net ionic equation assumes that all of the compounds are soluble in water. If any of the compounds are insoluble, a different approach is required.
