"Dry ice" experiment
How dry ice reacts with water and indicators
The very name DRY ICE sounds a little strange, doesn’t it? We’re used to ice melting rapidly and turning into ordinary water… But here it’s all a lot more complicated. Yes, dry ice is actually gas! So this ice doesn’t melt, but sublimes – it moves right from a solid state to a gaseous state! In this experiment, we examine different physical and chemical properties of dry ice.
#Step -by-step instructions
Take a piece of dry ice and place it on a metal spoon. After a few seconds, it will start to jump and shake. Then put the dry ice in the glass bowl with water and observe the violent release of gas bubbles and white smoke. If you add a few drops of dish-washing liquid to the water, then a thick foam of soap bubbles full of white smoke appears.
#Pro cesses description
Dry ice is a very simple substance, the solid phase of CO₂. It is widely available and used to transport food products or clean industrial surfaces. But in the home laboratory, dry ice becomes an invaluable source of experiments. The trick of dry ice lies in the fact that it moves immediately from a solid phase to a gas phase, without an intermediary liquid phase (this process is known as sublimation). The temperature of the sublimation of carbon dioxide is -78,5°С.
#Safe ty precautions☢☢☢ Use gloves and never let dry ice touch the skin for a long period of time. It has a temperature of -78,5 С, and you may receive a cold burn. Try not to breathe in CO2 gas – it may cause headaches.
We are so pleased with the results of our recent Twitter poll. No one who participated said that they were 'Disappointed' with their GCSE results! In fact, a huge 73% said they were 'Happy' with their results! Excellent work 😀 •
