Chemical experiments Experiments on mixing white vinegar and baking soda Solve

First there is precipitation, the carbon dioxide generated by combustion and calcium hydroxide react to produce calcium carbonate precipitation, because the cup covers the candle flame to isolate the oxygen, so the candle will be extinguished, pour white vinegar after the precipitation disappears, bubbles, because the acidity of acetic acid is stronger than carbonic acid, in line with the principle of strong acid to produce weak acid, so carbon dioxide gas will be generated.

At first, the CO2 produced by the burning of the candle reacts with the clarified lime water in the cup to form calcium carbonate, and you will see the cloudiness on the cup (a bit like making chalk into grinding water, but only a small amount). If you put acetic acid in a cup with a candle, the cloudiness will disappear because carbon dioxide reacts with water and calcium carbonate to produce calcium bicarbonate, which is produced by the burning of candles. Wish.

After mixing baking soda and white vinegar, CO2 gas will be produced, and CO2 can make the clarified lime water turbid, so when baking soda and white vinegar are mixed, gas will be seen, and then this gas will be passed into the clarified lime water, and the clarified lime water will become turbid.

There was nothing in the first cup. There is sediment in the second cup. Chen Qing lime water became turbid, we did the experiment today. Wish.

Baking soda reacts with vinegar to produce carbon dioxide!! Carbon dioxide is denser than air, and it can make the clarified lime water turbid.

Prepare two drink bottles, preferably with a wide mouth, to facilitate the punching of the cap, the punching method is very simple, with a red-hot screwdriver. The catheter is then inserted to ensure that the contact with the cap is tightly closed and does not leak. Tie a balloon to the right orifice and witness the results.

Then add baking soda to the left bottle first, and put the right bottle to clear.

The first one hasn't changed....The second flame is reduced to extinguished....Bonus points.

1. Produce many bubbles. The main ingredient of white vinegar is acetic acid, which is an acidic substance, while the main chemical of baking soda is sodium bicarbonate, which is a small white crystal that is soluble in water and is an alkaline substance. If you pour white vinegar and baking soda into a basin together, the two will react and produce many bubbles, like a volcanic eruption, that is, a chemical reaction.

2. Can white vinegar and baking soda be disinfected together?

OK. White vinegar and baking soda can be used together, a large number of bubbles produced by the two, with the effect of cleaning and sterilization, is also the main detergent, and the ingredient of baking soda, sodium bicarbonate itself has the effect of cleaning and deodorizing, and can also soften the water quality, and it is not easy to form dirt.

No, white vinegar has no color, it is to see the color of the experiment.

Fun challenge: After mixing white vinegar and baking soda, you can complete the experiment of turning vinegar into ice?
