Coffee is acidic, typically with a pH between 4.5 and 6.0. When blue litmus paper is exposed to coffee, it may turn red, indicating the presence of acids. This color change is due to the acidic nature of coffee, which causes the blue litmus paper to react and signal a lower pH.

What color does blue litmus paper turn when dipped in coffee?
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.
What is the effect of coffee on litmus paper?
Coffee is typically acidic, with a pH level around 4.5 to 6, depending on the type and preparation. When litmus paper, which is used to test acidity or alkalinity, is exposed to coffee, blue litmus paper will turn red, indicating acidity. Conversely, red litmus paper will remain red, as it does not indicate a basic solution. Thus, coffee can be identified as an acidic substance using litmus paper.
What effects does calcium hydroxide has on red and blue litmus paper?

What will be the effect of sodium hydroxide in blue litmus paper?
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
