Tonic water is usually acidic due to the presence of carbonic acid and citric acid, so pH paper will likely turn a color indicating acidity such as red or pink.
Bases turn pH paper blue or purple in color.
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. Some types of Litmus paper will not change color in pure water (such as the 1-12 pH yellow litmus paper), others will turn a purple color as an indication of the solution being not an acid (red) or a base (blue).
Pink cobalt chloride paper will turn blue when exposed to water. Cobalt chloride is a chemical compound that changes color based on the amount of water present, with pink indicating a dry condition and blue indicating the presence of water.
either colorless or a color between red and blue
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. -- Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.
blue
It would turn Green
If it is pure water, it doesn't change.
dark green
Tonic Water In Fact is non- alcoholic. It can be when mixed with alcoholic mixes such as vodka,wine,or beer. Tonic Water is not water made really for drinking plainly purposes. It is made to be mixed with alcoholic beverages. Hope this answered your question?
It depends whether the water is pure (Green) or with alkalis in it (Blue)
Bases turn pH paper blue or purple in color.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
A cobalt chloride paper will turn pink when exposed to water vapor. This color change is due to the cobalt chloride reacting with the water vapor to form pink cobalt chloride hexahydrate.
The paper turn to a blue color.
The water solution of iodine turn blue litmus paper to red.
