Blue
pH paper will turn red when put in vinegar, indicating that vinegar is acidic.

Litmus paper is reactive to acids and bases. Acids make the paper turn red; bases make it turn blue.
When acid comes into contact with pH paper, the paper changes color depending on the level of acidity. The paper may turn a different color to indicate the acidity level of the substance being tested.
If a base is applied to litmus paper, it will turn the litmus paper blue. This color change occurs because bases typically have a pH greater than 7 and cause litmus paper to turn blue to indicate their basic nature.
it can turn red pH paper blue and blue pH paper red
pH paper will turn red when put in vinegar, indicating that vinegar is acidic.
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
The color of indicators is changed by acids and bases due to their ability to alter the pH of a solution. Acids typically turn pH indicators like litmus paper red, while bases turn them blue. The specific color change depends on the type of indicator used, as different indicators have unique pH ranges for color changes. Therefore, both acids and bases can affect the color of indicators.

This color depends on the pH of the solution.
Litmus paper is reactive to acids and bases. Acids make the paper turn red; bases make it turn blue.
When dipped in coffee, pH paper will change color based on the acidity or alkalinity of the coffee. If the coffee is acidic, the pH paper will turn a different color than if it is alkaline. This color change indicates the pH level of the coffee.
When acid comes into contact with pH paper, the paper changes color depending on the level of acidity. The paper may turn a different color to indicate the acidity level of the substance being tested.
No change occur.
The color of pH paper when dipped in well water depends on the water's pH level. If the well water is neutral, the pH paper will typically turn green, indicating a pH of around 7. If the water is acidic, the paper may turn red, while alkaline water will cause it to turn blue. To determine the exact pH, you would need to compare the color change to a pH scale provided with the paper.
If a base is applied to litmus paper, it will turn the litmus paper blue. This color change occurs because bases typically have a pH greater than 7 and cause litmus paper to turn blue to indicate their basic nature.
