A base will appear as a blue or purple color on pH paper. This is due to the indicator dye in the paper changing color in the presence of a basic solution.
Litmus paper is an indicator paper that turns blue in the presence of a base. It is used to test the pH of a solution, with blue indicating a basic pH.
To determine the pH of a weak base, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak base and its equilibrium constant.
pH test paper is typically made of paper that is impregnated with a universal indicator, which changes color to indicate the pH of a solution. It is not an acid or a base itself, but rather a tool used to determine the acidity or alkalinity of a substance.
The pH of orange juice varies from about 3.3 to 4.2, which makes it weakly acidic. This would be orange on many UI papers, but they do vary so always compare the colour with the chart supplied.
A pH indicator like litmus paper can best show a change from an acid to a base. Litmus paper is red in acidic solutions and blue in basic solutions, making it easy to visually detect the shift in pH.

pH paper and litmus paper
Litmus paper is an indicator paper that turns blue in the presence of a base. It is used to test the pH of a solution, with blue indicating a basic pH.
Litmus paper will determine acid or base. Universal indicator paper (pH paper) will give an answer to the nearest whole number.
To determine the pH of a weak base, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak base and its equilibrium constant.
by using an indicator like litmus paper!!!

Paper that is blue will turn/stay _____ in the presence of a strong base.
Because pH paper doesn't like to get dipped.
The pH of orange juice varies from about 3.3 to 4.2, which makes it weakly acidic. This would be orange on many UI papers, but they do vary so always compare the colour with the chart supplied.
