coke being acidic will give a redish orange color on the pH strip.
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
The pH value is approx. 5.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
The answer isn't so simple. There are various kinds of pH paper. However, I presume you are referring to litmus paper which is the widest distributed form. Acetic acid has no effeect on red litmus paper but turns blue litmus red
Coffee is generally acidic, thus the blue litmus paper will turn red. However, the pH of coffee can vary depending on the kind. Dark roasted coffees tend to be more alkaline and the blue litmus paper may stay blue when dipped.

When pH paper is dipped into an acid, it changes color depending on the acidity of the solution. The paper turns a certain color (usually red) to indicate that the solution is acidic. The intensity of the color change corresponds to the pH level of the acid.
Because pH paper doesn't like to get dipped.
Blue litmus paper turns pink when dipped into a base. This is because the color change indicates a shift in pH level from acidic to basic.
When dipped in lemon juice, pH paper typically turns red or pink. This indicates that the lemon juice is acidic.
blue, indicating a basic pH.
PH paper will turn dark blue or purple when dipped in potassium hydroxide powder, indicating a high pH level.
When dipped in ammonia, pH paper will turn blue or blue-green. This color change indicates that the solution is basic or alkaline due to the presence of ammonia.
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
Coffee has an acidic pH - red with litmus paper.
Coffee is acidic due to its pH value ranges typically from 4.85 to 5.10. On pH paper with a pH value of 5, coffee would likely turn red or a shade of pink indicating its acidity.
