A moist litmus paper does not change its colour in neutral solutions.
When you dip pH paper in milk, you will generally observe a neutral pH reading, around 6 to 7, depending on the specific composition of the milk. This is because milk is slightly acidic to neutral. The pH paper may turn a light green or yellowish-green, indicating its neutral to slightly acidic nature. However, the exact color can vary based on the type of pH paper used.
Nitrogen gas (Nā) does not change the color of moist red litmus paper. This is because nitrogen is a neutral gas that does not have acidic or basic properties. Therefore, it will not cause any color change in the litmus paper.
The green color on litmus paper with tap water typically indicates a neutral pH level. The tap water may have a pH close to 7, resulting in the green color change. This means the water is neither acidic nor basic.
Barium nitrate will not change the color of blue litmus paper. It is a neutral salt and does not produce an acidic or basic solution when dissolved in water. Therefore, blue litmus paper will remain blue when exposed to a barium nitrate solution.
The color not change.
in neutral solutions ph paper turns to blue!
in neutral conditions there is no change in colour of litmus....
red, acid is mainly red and alkali is blue/purple neutral is green and it all dpends on the ph of the substance
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. -- Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.
blue
Litmus paper turns red when exposed to an acidic solution and blue when exposed to a basic solution. Common salt (sodium chloride) is neutral, so it does not significantly change the color of litmus paper.
if you are working with a strong acid the lithmus paper will turn red.
There will not be any colour change.
it turns blue litmus paper red
Green
BLUE
It's purple the colour can change slightly. isn't that just great purple it's my favourite colour ya know
