Focus Question: How does the bonding of baking soda and vinegar create a reaction based on the elements they are made of and polarity?
The reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid)
When combined, the hydrogen atom in the acetic acid meets up with the hydrogen and oxygen atoms in the baking soda to form a molecule of water, while the acetate ion grabs onto the sodium atom and forms a salt, sodium acetate. The carbon dioxide molecule, free of its other chemical bonds, can now escape, and bubbles forth as a gas.
Dissolving ionic compounds causes the two ions to separate. Dissolved baking soda dissociates into a sodium and a bicarbonate ion:
sodium bicarbonate —-> sodium ion + bicarbonate ion: NaHCO3 —-> Na+ + HCO3
the bicarbonate doesnot break into smaller pieces? Because it’s atoms are bonded together more tightly by covalent bonds.
Similarly, the acetic acid in vinegar dissociates into:
acetic acid —-> hydrogen ion + acetate: CH3COOH —-> H+ + CH3COO
- The chemical name for baking soda is sodium bicarbonate. Its chemical formula is NaHCO3, meaning it's made of one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. Vinegar is a mixture of acetic acid and water. Dilute acetic acid is the chemical name for vinegar, and its chemical formula is CH3COOH, meaning it's made of two carbon atoms, four hydrogen atoms, and two oxygen atoms.
- Baking soda is a base, and vinegar is an acid. An acid is a chemical that wants to get rid of a proton, or a positively charged hydrogen atom. A base is a chemical that wants a proton. When you mix an acid with a base, the acid is ready to give away its proton and the base is ready to take it.
- They react because baking soda is a base and vinegar is an acid dissolved in water. When you mix an acid and base together the elements in them are polar to certain other elements, causing This means that some of the elements between baking soda and vinegar were more attracted to the water causing some elements to break down and others to combine together due to polarity and cause a reaction.
- When we mix baking soda and acetic acid in water together, acetic acid gives its proton to the broken-apart baking soda and together, they form sodium acetate (CH3COONa), water (H2O), and carbon dioxide (CO2). These products are created quickly, and the carbon dioxide comes out as a gas.
