Does baking soda and vinegar have a complete ionic equation?
HC2H3O2 (aq) + NaHCO3 ===> NaC2H3O2(aq) + H2CO3(aq)----->H2O(l)+CO2(g)+2H2O(l)
The chemical reaction between vinegar (HC2H3O2) and baking soda (NaHCO3) does result in a complete ionic equation. Here's the breakdown of the reaction:
1. The reactants are acetic acid (HC2H3O2) and sodium bicarbonate (NaHCO3).
2. Acetic acid dissociates into hydrogen ions (H+) and acetate ions (C2H3O2-).
3. Sodium bicarbonate dissociates into sodium ions (Na+) and bicarbonate ions (HCO3-).
4. The hydrogen ions from the acetic acid combine with the bicarbonate ions, forming carbonic acid (H2CO3).
5. Sodium from the sodium bicarbonate combines with the acetate ions, producing sodium acetate (NaC2H3O2).
6. The carbonic acid then decomposes into water (H2O) and carbon dioxide gas (CO2).
7. The overall equation is:
HC2H3O2 (aq) + NaHCO3 (aq) → NaC2H3O2 (aq) + H2CO3 (aq) → H2O (l) + CO2 (g) + NaC2H3O2 (aq)
Note that the formation of carbon dioxide gas is indicated by (g), and the formation of water is indicated by (l).
Yes, baking soda (sodium bicarbonate, NaHCO3) and vinegar (acetic acid, HC2H3O2) do have a complete ionic equation. Let's break it down step by step to understand how to write a complete ionic equation.
First, let's write the balanced molecular equation:
HC2H3O2(aq) + NaHCO3(s) → NaC2H3O2(aq) + H2CO3(aq)
In this equation, the (aq) represents substances that are dissolved in water (aqueous solutions). The (s) represents a solid state.
Next, let's determine the ionic compounds that dissociate into ions in the aqueous solutions. In this case, HC2H3O2 dissociates into H+ and C2H3O2- ions, while NaHCO3 dissociates into Na+ and HCO3- ions.
Therefore, the complete ionic equation can be written as:
H+ + C2H3O2- + Na+ + HCO3- → Na+ + C2H3O2- + H2CO3(aq)
Now, let's simplify the complete ionic equation by removing the spectator ions. Spectator ions are those ions that remain unchanged throughout the reaction and do not participate in any chemical reaction. In this case, Na+ and C2H3O2- ions are spectators.
So, the simplified complete ionic equation is:
H+ + HCO3- → H2CO3(aq)
Therefore, the complete ionic equation for the reaction between baking soda and vinegar is:
H+ (aq) + HCO3- (aq) → H2CO3 (aq)
It is important to note that in the actual reaction, carbonic acid (H2CO3) decomposes into water (H2O) and carbon dioxide gas (CO2). So, the final products will be H2O(l) + CO2(g).
The ionic equation is
HC2H3O2 + Na^+ + HCO3^- ==> H2O + CO2 + Na^+ + C2H3O2^-
To fine the NET ionic equation, just cancel the Na^+ on the left and right sides. What is left is the net ionic equation.
HC2H3O2 + HCO3^- ==> H2O + CO2 + C2H3O2^-
