Distilled Water Colour On Ph Paper

The ph value of distilled water is theoretically 7 neither acid or base.
Distilled water colour on ph paper. A acid has ph range from 0 6. The strip will change color gradually. The ph value can vary from 0 to 14. Fill a container with distilled water.
Solutions with a ph between 0 and 7 are acidic while those with a ph between 7 and 14 are basic. D rest all are bases. Litmus paper may be dampened with distilled water to give a color change for a gaseous sample. Gases change the color of the entire litmus strip since the whole surface is exposed.
Acids change ph paper red. Determine the ph level of the water by. Actually sodium chloride is a salt prepared from strong base naoh and strong acid hcl. D acids turn ph paper strip red.
A water is neutral and the colour of ph paper for neutral solutions is green. There will not be any change in the colour of the ph paper. C ph paper is blue in base and rest are acids. Neutral gases such as oxygen and nitrogen do not change the color of the ph paper.
However as soon as distilled water is exposed to air it begins dissolving carbon dioxide and starts shifting to become slightly acidic. It is a neutral salt and is not expected to bring any change in the ph of distilled water. C naoh is base and base turns ph paper into blue colour. So when the paper is dipped in a solution the colored part of the paper changes color.
Ph paper comes with a color chart to help you ascertain the ph level of the water. Dip a test strip into the water. It will remain green which indicates that the solution has maintained neutral character. Pure distilled water should be neutral with a ph of 7 but because it absorbs carbon dioxide from the atmosphere it s actually slightly acidic with a ph of 5 8.
Hence the ph will decrease with addition of acid in water.
