Litmus paper turns blue in basic solution.
To determine the pH of a solution using pH indicator paper, you would first dip the paper into the solution. The paper will change color based on the acidity or alkalinity of the solution. You can then compare the color of the paper to a pH color chart to determine the approximate pH level of the solution.
The paper sank in the buffer solution because paper is denser than the liquid in the buffer solution. The density of the paper caused it to displace an equal volume of liquid, resulting in the paper sinking rather than floating.
The PH paper soaks up the solution & tests the liquid, the pH paper will then change colour to show what the solution contains. Although if the paper stays the same colour it means the solution is nutral & safe.
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.
