If you mix KC2H3O2 and BaCl2 what is the molecular equation?
I got 2 KC3H3O2 (aq) + BaCl2 (aq) --> 2 KCl (aq) + Ba(C2H3O2)2 (aq) but I don't know if it is correct. My teacher just gives examples and doesn't explain how to do this.
Personally, I don't think a reaction will occur. No precipitate (insoluble material) is formed, no gas is formed, and I believe both of the products listed are strong electrolytes.
Reasons for a reaction to proceed are as follows:
1. A ppt is formed.
2. A gas is formed.
3. A weak electrolyte is formed.
4. Redox reactions have separate rules.
To determine the molecular equation for the reaction between KC2H3O2 (potassium acetate) and BaCl2 (barium chloride), you need to consider the combination of the cations (positive ions) and anions (negative ions) in the reactants and products.
First, write out the chemical formula for each compound:
- KC2H3O2 consists of the K+ cation (potassium) and the C2H3O2- anion (acetate).
- BaCl2 consists of the Ba2+ cation (barium) and two Cl- anions (chloride).
Next, determine the balanced molecular equation by swapping the cations and anions from each reactant to form new compounds:
- The K+ cation from KC2H3O2 combines with the Cl- anion from BaCl2 to form KCl (potassium chloride).
- The Ba2+ cation from BaCl2 combines with the C2H3O2- anion from KC2H3O2 to form Ba(C2H3O2)2 (barium acetate).
The balanced molecular equation for the reaction is:
2 KC2H3O2 (aq) + BaCl2 (aq) -> 2 KCl (aq) + Ba(C2H3O2)2 (aq)
So, your molecular equation is indeed correct!
