Carbon dioxide is a colorless gas.
Cobalt chloride paper turns from blue to pink in the presence of water. Limewater turns cloudy in the presence of carbon dioxide.
No, hydrogen carbonate indicator does not change color when exposed to oxygen. It is mainly used to detect the presence of carbon dioxide, as it turns pink in the presence of an acid (carbon dioxide dissolved in water forms carbonic acid).
Phenolphthalein turns pink in basic solutions
Phenolphthalein turns pink in the presence of a base or any solution with a ph over 7.
i turns yellow and it turns pink when you add acids

Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
Phenolphthlalein is something like a pH indicator. When it is added to a liquid and the liquid turns pink, it means that the latter substance is basic.When the solution is added with NaOH, it will turn pink.Note that NaOH serves as a carbon dioxide neutralizer.The color of the solution will slowly fade after some time, because carbon dioxide is present in the air neutralizing the color effect of the NaOH.
As soda contains carbon dioxide, it's actually a dilute solution of carbonic acid, hence phenolphthalein remains colourless.
Pink Turns Blue was created in 1985.
carbon dioxide or CO2 (can be indicated with limewater...starts clear and becomes cloudy) and water vapor or H2O (can be indicated with cobalt chloride...turns from light blue to pink)
Reddish pink limestone
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
Venus is known for its pinkish sky, caused by its thick atmosphere of carbon dioxide and clouds of sulfuric acid that scatter light in a way that creates a pink hue.
When pink is bleached, it typically turns white.
No, ammonia does not turn phenolphthalein pink. Phenolphthalein is a pH indicator that turns pink in basic solutions, but ammonia is a weak base and typically does not have a strong enough pH to turn phenolphthalein pink.
