Write the net ionic equation for the precipitation of manganese(II) carbonate from aqueous solution:
See your previous posts.
To write the net ionic equation for the precipitation of manganese(II) carbonate from aqueous solution, we need to first write the balanced equation for the reaction.
The reaction occurs between the manganese(II) ions (Mn2+) and carbonate ions (CO32-) in solution. The balanced equation for the reaction would be:
Mn2+ + CO32- -> MnCO3
Next, we need to determine if any of the reactants or products fully dissociate in the solution. In this case, both manganese(II) ions and carbonate ions are typically soluble in water, so they will dissociate completely. Therefore, there are no spectator ions to remove from the equation.
Finally, we can write the net ionic equation by omitting the spectator ions:
Mn2+ + CO32- -> MnCO3
This is the net ionic equation for the precipitation of manganese(II) carbonate from aqueous solution.
To write the net ionic equation for the precipitation of manganese(II) carbonate, we need to consider the reaction between the cations and anions involved in the formation of the precipitate.
First, let's examine the solubility rules to determine if manganese(II) carbonate is soluble or insoluble. According to the solubility rules, most carbonates are insoluble except for those of Group 1 elements (Li+, Na+, K+, etc.) and ammonium (NH4+). Manganese(II) is not a Group 1 element or ammonium, so it is reasonable to assume that manganese(II) carbonate is insoluble.
Knowing that manganese(II) carbonate is insoluble, we can proceed to write the balanced molecular equation for the reaction:
Mn2+ (aq) + CO3^2- (aq) -> MnCO3 (s)
Next, let's break down the reactants and products into their respective ions to identify the spectator ions:
Mn2+ (aq) + CO3^2- (aq) -> MnCO3 (s)
The only ion in the reaction that undergoes a change is the manganese(II) cation (Mn2+), while the carbonate anion (CO3^2-) stays the same. Therefore, the carbonate ion acts as a spectator ion.
Now, let's write the net ionic equation by eliminating the spectator ion:
Mn2+ (aq) -> MnCO3 (s)
So, the net ionic equation for the precipitation of manganese(II) carbonate from aqueous solution is:
Mn2+ (aq) -> MnCO3 (s)
