The acidity or alkalinity of a solution, pH indicator.
Using a UI indicator solution, or UI paper, pH 6.7 corresponds to a yellow/green colour
Get a filter funnel and filter paper and pour in solution . water will run through and salt left behind
an indicator is capable of determining if a substance is basic or acidic or neutral. if you are just looking for if it is a basic or acidic. then you could you could use red litmus or blue litmus. if you are looking for the pH of a substance try using: red cabbage indicator phenolphthalein i hope i answered your question!

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.
If the substance is in liquid form, the pH may be determined by litmus paper.
Suger solution made with water is homogenous so,nothing left, seperate with filter paper .
The blank solution is used to be compared with a solution containing a component to be determined; the blank solution is supposed to be uncontaminated by this substance. The blank solution is important for the calibration of instruments.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
The acidity or alkalinity of a solution, pH indicator.
The red litmus paper remain red in acidic solutions, under a pH=4,3 at 25 oC.
No.
Some disadvantages of using pH paper is when the pH paper is exposed to air for too long it collects other molecules in the air and when a solution is put on top of the paper it mixes with the other molecules creating a new solution, throwing off the measurements and ruining the experiment.

a grease spot would be observed on the paper as if you as to put something that was fried in oil on grease proof paper proving that the solution is an oil,It would be transparent
