What is the indicator paper that turns blue in base?
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.
How can one determine the pH of a weak base?
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.
Is pH test paper an acid or a base?
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.
What color does the pH paper change in orange juice?
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.
Which indicator would be the best to show a change from an acid to a base?
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.
What color is base on pH paper?

Why is dipping pH paper into solns bad?

How can you tell if something is a acid or base?
A PH meter or litmus paper.
What is the best way to determine whether a substance is an acid or base?
A pH meter gives a direct reading which is great when testing wine or soft drinks. Litmus paper will go red in acid or blue in base. An acid will liberate carbon dioxide from chalk - a base will not You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic. Turmeric indicates acid by turning strong yellow. Base is indicated by red. Phenolphthalein indicates bases by turning red or purple. Acid is indicated by no color.
