What is the net ionic equation of potassium carbonate combines with strontium hydroxide?
To determine the net ionic equation for the reaction between potassium carbonate (K2CO3) and strontium hydroxide (Sr(OH)2), we first need to write the balanced molecular equation:
K2CO3 + Sr(OH)2 -> 2KOH + SrCO3
Next, we need to identify the dissociated ions in the reaction. In this case, potassium hydroxide (KOH) is a soluble compound and dissociates into its constituent ions:
KOH -> K+ + OH-
However, strontium carbonate (SrCO3) is insoluble and does not dissociate into ions.
By looking at the dissociated ions, we can now write the net ionic equation:
2OH- + Sr2+ -> Sr(OH)2
So, the net ionic equation for the reaction between potassium carbonate and strontium hydroxide is:
2OH- + Sr2+ -> Sr(OH)2
To determine the net ionic equation of the reaction between potassium carbonate (K2CO3) and strontium hydroxide (Sr(OH)2), we need to first write the balanced chemical equation for the reaction.
The chemical formula for potassium carbonate is K2CO3, and strontium hydroxide is Sr(OH)2. When these two compounds react, they combine to form strontium carbonate (SrCO3) and potassium hydroxide (KOH).
The balanced chemical equation for the reaction can be written as:
2K2CO3 + Sr(OH)2 -> SrCO3 + 4KOH
Now, let's determine the ions present in the reaction. When potassium carbonate dissolves in water, it ionizes into potassium ions (K+) and carbonate ions (CO3^2-). Likewise, strontium hydroxide dissociates into strontium ions (Sr^2+) and hydroxide ions (OH-).
The complete ionic equation for the reaction is:
2K+ + CO3^2- + Sr^2+ + 2OH- -> SrCO3 + 2K+ + 2OH-
Now, let's simplify the equation to obtain the net ionic equation, which shows only the species that participate in the reaction:
CO3^2- + Sr^2+ -> SrCO3
In the net ionic equation, the potassium ions (K+) and hydroxide ions (OH-) on both sides of the equation have canceled out because they appear on both the reactant and product sides.
Therefore, the net ionic equation for the reaction between potassium carbonate and strontium hydroxide is:
CO3^2- + Sr^2+ -> SrCO3
