When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution.
We've used vinegar in some of our science experiments before: with Jello powder and baking soda for colorful and scented bubbles, with glitter and baking soda for sparkly eruptions, and with color changing bath tablets for a color mixing activity. We also very recently made a classic play dough volcano!!
In our case, baking soda is sodium bicarbonate (a base) and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide. This makes the reaction bubble and expand, just like when you shake up a can of soda and open it!
Instead of using vinegar, use ketchup with baking soda. This is perfect for a volcano effect because the ketchup is already the right color. You can also add liquid dish soap to create more bubbles and foam in the eruption.
Always keep the ratio one-part baking soda to two parts vinegar.
Conclusion. The experiment and result of it supported our hypothesis that the bubbles would float on top of the mixture of the baking soda and vinegar. It did this because when we combined the baking soda and vinegar it had a chemical reaction that produces carbon dioxide gas.
First, mix just enough baking soda with water to make a paste. Add a couple of drops of red food coloring and mix. Place your heart cookie cutter into your dish and place the baking soda paste into the cookie cutter. Mash the paste with your fingers to mold it to the heart shape.
As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption.
So what happens if you drink coke and eat Mentos? You'll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. The sudden swell of carbon dioxide inside your stomach will need an escape.
Pouring milk in Coke or vice versa results into a reaction of phosphoric acid in the Coke to milk's proteins causing them to stick together, creating dense lumps that later settle at the bottom. In short, the milk curdles up.
That's because cola has acid in it – phosphoric acid, to be precise. Most colas have a pH of 2.5-3.5. When the copper oxide (the pennies) and the phosphoric acid (the cola) get together in the bath, the acid reacts with the copper oxide on the pennies and dissolves it. That's why the pennies get shiny.
Step 1: Remove the lid from the Diet Coke and set it the bottle of soda on a flat surface.
- Step 2: Roll the paper into a tube around a pack of Mentos mints, tape it into place and pull it off of the roll of mints.
- Step 3: Hold your finger over one end of the paper tube and have your child fill it up with Mentos mints.
Milk Coke is exactly that. Milk and Coca-Cola, mixed together and drunk. It is apparently a thing in Birmingham, and not the first of its kind; a quick search sent me down a wormhole of other milk and fizz combinations, including my personal favourite, Bena milk, which is Ribena mixed with milk instead of water.
This happens thanks to the phosphoric acid in Coca-Cola, which dissolves the iron(III) oxide. Bleach contains sodium hypochlorite, which is a strong oxidizing agent and easily oxidizes the coloring molecules in the Coca-Cola, causing it to pale. The main ingredients of classic Cola are sugar and water.
Nothing dangerous happens when you mix baking soda and vinegar, but basically they neutralize each other and you lose all the beneficial aspects of the two ingredients.
Combining baking soda and vinegar is a natural way to dissolve hair clogs, without resorting to harsh chemicals.
The bubbling reaction from the baking soda and vinegar helps to loosen the drain clog, and the boiling water in step 4 helps remove it from your pipes. Baking soda and vinegar can serve as a natural drain cleaner.
Although vinegar and baking soda are safe to use in both regular and HE washing machines, they are considerably less efficient than high-performance laundry detergents at delivering an outstanding and odorless clean.
When the vinegar and salt dissolve the copper-oxide layer, they make it easier for the copper atoms to join oxygen from the air and chlorine from the salt to make a blue-green compound called malachite.
For the eruption:
- Small bowl.
- Cup.
- 1 tbsp bicarbonate of soda (baking soda)
- 1 tbsp washing up liquid.
- 2 tbsp water.
- ½ cup vinegar.
- 1 tbsp red food colouring.
Tell students that cream of tartar is a dry acid and that, when mixed with water, it reacts with baking soda to produce carbon dioxide gas. This is very similar to the way vinegar (a solution of acetic acid) reacts with baking soda to produce a gas.
While both products appear similar, they're certainly not the same. Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated.
We had eruptions from 4 out of 6 tests! Water, vinegar, baking soda solution and juice all reacted. The best, and longest lasting reaction came from the juice! A key finding we had was that baking powder gives a very long and sustained reaction.
Pour about 1 inch of vinegar into your 2-liter soda bottle using a funnel. Clean and dry your funnel. Add 2 tablespoons of baking soda into the soda bottle slowly using your funnel. The baking soda and vinegar will fizz.
