Red
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.
Dishwater detergent with a bit of water would be in the pH range of 3-6.
Sulfuric acid will turn red on pH paper, indicating a very low pH level, typically around 0-1.
Sodium carbonate is a basic compound, so it will turn pH paper blue in color.
The pH of sugarcane juice is typically around 5.5 to 6.5, making it slightly acidic. This would result in a pH paper color of red to orange.
This depends on the kind of pH paper.
in neutral solutions ph paper turns to blue!
Red
It Should be about 2
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.
It depends on its nature either it is concentrated or dilluted but most of the time it shows red colour on pH paper
Dishwater detergent with a bit of water would be in the pH range of 3-6.
This color depends on the pH of the solution.
Depending on the type of soil, the value of pH and the type of pH paper. For an acid soil the pH paper from Merck (art. 9565) this color will be probable green.
not quite sure...
The paper will become orange in colour.
Mosambi juice is typically acidic, so it would turn red on pH paper.
