Red/pink for litmus indicators. Other indicators such as methyl orange will display different colours.
pH food coloring is a type of food coloring that changes color based on the acidity or alkalinity of a substance. It is commonly used in educational settings to demonstrate pH levels through color changes.
Phenol red is a red color at neutral pH. It changes color depending on the pH of the solution it is in.
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.
Soy sauce typically has a pH of around 4.0 to 4.5, which falls within the acidic range. The color of soy sauce is usually dark brown, and the pH of the sauce does not affect its color.
Using a UI indicator solution, or UI paper, pH 6.7 corresponds to a yellow/green colour
Red - pH 1 (acidic) Green - pH 7 (neutral) Blue - pH 12 (basic)

That depends on the pH.
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.
pH can be determined experimentally by using a pH meter or pH paper. A pH meter measures the concentration of hydrogen ions in a solution, while pH paper changes color based on the acidity or alkalinity of a solution. By comparing the color of the pH paper to a color chart or by reading the pH value on the meter, the pH of a solution can be determined accurately.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
Soy sauce typically has a pH of around 4.0 to 4.5, which falls within the acidic range. The color of soy sauce is usually dark brown, and the pH of the sauce does not affect its color.
The color of a pH strip will vary from red to violet when exposed to either an acidic or alkaline solution. Water with a pH level of 9.5 is more alkaline and would show up as blue in color.
Using a UI indicator solution, or UI paper, pH 6.7 corresponds to a yellow/green colour
Bases turn pH paper blue or purple in color.
