Well, for starters, I assume that you already know that dry ice, as it is commonly called, is frozen CO2. Second, I assume that the CO2 that you are referring to is in a gaseous state. If these assumptions are true, then mixing dry ice and CO2 would accomplish next to nothing. The gaseous CO2 would get colder, and the dry ice would sublime faster or slower, depending upon the surrounding temperature before adding the gaseous CO2 compared to the temperature of the gaseous CO2. If warmer, it would sublime faster. If colder, it will sublime slower.
It turns back to purple, because dry ice has a PH of 7, neutral.
It is not recommended to mix dry ice with normal ice because dry ice is extremely cold (-78.5°C or -109.3°F) and can cause the water from the normal ice to freeze quickly. This could create a hazardous situation and increase the risk of frostbite or injury. It's best to use dry ice separately and handle it with care.
When liquid CO2 is exposed to air, it quickly evaporates and turns into gaseous CO2. This process is known as sublimation. The gaseous CO2 will mix with the air in its surroundings.
Pieces of dry ice, otherwise known as solid carbon dioxide, become smaller through the process of sublimation. This is the physical change of matter from solid to gas. When combined with water, a mix of humid air and CO2 is created. The water then condenses creating fog.
The answer below this paragraph is in error. It applies to CO (Carbon Monoxide), not CO2 (Carbon Dioxide), even though both gases are produced by burning fossil fuels. The inhalation of excessive CO2 can indeed poison a person, but in a very different way. CO2 can combine with the water in our bodies to produce Carbonic Acid (CH2O3); we can tolerate the amount of acid produced by breathing the minute quantities of CO2 in natural air, but if the air reaches 1% problems occur, beginning with drowsiness. At 5%, a person can die from the acidosis that has already begun to set in at 3%. You can look up the details yourself. As for breathing the fumes of dry ice, the problems caused are mostly related to the extreme cold if you get too close to the source. However, if a person persists in breathing the heavier CO2 from the dry ice, he can indeed incur some degree of poisoning as described above. If you only breathe this gas, then you will quickly die off. It will attach itself to the hemoglobin in the blood and hinder the hemoglobin in transporting oxygen so even breathing a mix of this gas for any length of time is highly dangerous. Dry Ice is made of frozen stiff CO2. Fumes from a car is very dangerous to breathe for any length of time especially because of CO2 and its ability to attach to the hemoglobin in the blood. The gas itself does not kill fast. It will just slowly fill up the blood plates with CO2 and since this does not give energy to our cells, the blood plates do not get rid of it on their way to the lungs again for a refill of oxygen. As time goes, more and more of the blood plates transports a payload they can not get rid of. More and more cells are deprived of oxygen and in the end you faint and eventually die. Fortunately (for most) this gas is heavier than air we breathe and will only reach us to the top of the toes and the wind will quickly blow it away. A lot of this gas indoor however causes a bigger risk. Be sensible when playing with this type of ice. It is fun to put in water but not fun to breathe in its "fumes".
Comet ice is a mix of water ice (H2O) and dry ice (CO2).
When carbon dioxide (CO2) and water (H2O) mix, they can undergo a chemical reaction to produce carbonic acid (H2CO3). This reaction is important in natural processes such as the dissolution of CO2 in seawater, which helps regulate the Earth's climate.
It turns back to purple, because dry ice has a PH of 7, neutral.
When you mix chocolate milk and dry ice, the dry ice, which is solid carbon dioxide, sublimates and turns into gas, creating bubbles and fizzing in the liquid. This reaction can produce a dramatic visual effect, as the gas forms a thick fog or vapor that can spill over the container. However, it's essential to handle dry ice carefully, as it can cause frostbite if touched directly, and the resulting mixture should not be consumed until the dry ice has completely dissipated.
It is not recommended to mix dry ice with normal ice because dry ice is extremely cold (-78.5°C or -109.3°F) and can cause the water from the normal ice to freeze quickly.

If a person took dry ice into his mouth, he would kill all the tissue that the dry ice touched, and could possibly die. If you even touch dry ice, it is so cold that it feels like it is burning you. Imagine what it could do to the thin, sensitive tissues in your mouth and throat.
You produce a lot of gas (CO2).
You can, the dry ice(solid form of carbon dioxide) will ultimately evaporate into carbon dioxide gas, and will then leave only the regular ice (frozen water). Because the dry ice will no longer exist, the regular ice will melt.
When You Mix Dry Ice And RootBeer, The Mixture Turns Into RootBeer Float, Or RootBeer Slushee, Or Whatever. The Temperature Of The Dry Ice Is So Cold, That The RootBeer Starts To Freeze, But Since It's Not Apart Of The RootBeer, It Cant Freeze It All The Way. -Signed, Brodie!
When liquid CO2 is exposed to air, it quickly evaporates and turns into gaseous CO2. This process is known as sublimation. The gaseous CO2 will mix with the air in its surroundings.
Carbonated water does not taste good. Have you ever gone to refill your soda and the syrup is out? All you will taste is the carbonated water, gross. Similarly if you put dry ice in a water cooler filled with regular water, the CO2 given off by the dry ice 'vaporizing' can mix with the water and cause it to taste like carbonated water if not allowed to vent. If the dry ice 'vaporization' is allowed to vent out then all you will taste is water, but it will be ice cold.
In the laboratory, cold fluids are commonly used. A mix of shaved ice and distilled water is used to establish the "triple point of water" - 0oC. A mix of alcohol and 'dry ice (solid CO2) is used to freeze out any water from a liquid. And liquid Nitrogen is used as very cold liquid to cool vacuum plant etc.
