Need Help Finishing:
Purpose:
• To observe a chemical reaction.
Materials:
• Vinegar (acetic acid, CH3COOH)
• Baking soda (NaHCO3)
• Measuring cups and spoons
• Cup
Procedure:
1. Place ½ cup of vinegar in the cup.
2. Add 1 tablespoon on baking soda.
3. Record your observations.
(Observed a bubbling with a rising of the liquid which
was carbon dioxide escaping)
Questions:
1. Write the balanced equation for the first step in the reaction between vinegar and baking soda, with carbonic acid (H2CO3) as a product. What type of reaction is this?
( HC2H3O2 + NaHCO3--->NaC2H3O2 + H2CO3 ,
which is double replacemtent...is this correct?
Need Help with the rest.......
2. Write the balanced equation for the second step in the reaction, the liberation of carbon dioxide from carbonic acid. What type of reaction is this?
3. Write the combined, balanced equation for the complete chemical reaction between vinegar and baking soda.
Rule: Acids react with carbonates to yeild a salt, carbon dioxide, and sometimes water.
In your supposed synopisis, where carbonic acid is formed, it decomposes to water and carbond dioxide.
To answer question 2, we need to determine the balanced equation for the liberation of carbon dioxide from carbonic acid.
The balanced equation for this step of the reaction is:
H2CO3 -> H2O + CO2
This is a decomposition reaction, where one compound breaks down into two or more simpler substances.
Now, let's answer question 3 and write the combined, balanced equation for the complete chemical reaction between vinegar and baking soda.
The balanced equation for the complete reaction is:
HC2H3O2 + NaHCO3 -> NaC2H3O2 + H2O + CO2
This is an example of a double replacement reaction (also known as a metathesis reaction) because the cations and anions of two different compounds exchange places to form new compounds.
Remember that when an acid reacts with a carbonate, it produces a salt, carbon dioxide, and sometimes water. In this reaction, vinegar (acetic acid) reacts with baking soda to form sodium acetate, water, and carbon dioxide gas.
this is a synthesis it is
