Product description
Litmus Paper | Kertas Litmus (Red & Blue)
Litmus Paper Concept:
Litmus paper is a water-soluble mixture of various pigments extracted from lichens.
Litmus Paper Function:
This mixture is usually absorbed by a filter paper which is then used as a pH indicator
to measure the pH and alkalinity of the materials. A blue litmus leaf turns red when exposed to acid,
and a red litmus leaf turns blue when exposed to an alkaline or basic substance.
Limitations Of The Litmus Test:
The test is quick and simple, but it has a few limitations.
Firstly it is not an accurate indicator of the pH. It does not give a numeric value,
instead indicating whether the sample is an acid or a base.
Second, the paper can change colors for other reasons besides the acid-base reaction. For example,
blue litmus paper turns white in chlorine gas. This color change is due to the bleaching of
the dye from hypochlorite ions, not the acidity and alkalinity.
Alternatives To Litmus Paper:
Litmus paper is useful as a base indicator for general acid, but you can get more
specific results if you use an indicator that has a more narrow test range. Orcein and
Azolitmin yield similar results to those found in litmus paper.
PH Paper Test Paper Litmus 1-14 Booklet
The test strip color changes must be matched with the pH scale color chart within about 15 seconds.
Different pH content discoloration range is different, by comparing the color card ratio: the smaller the number,
the stronger the acidity, the larger the value, the stronger the alkalinity.
Please do not dip the PH strips in the test liquid. It might lead to incorrectly showing test result.
Please drop the test liquid on the PH strips. It will perfectly indicates the real acidic or alkalinity substance.
There is a strong correlation between the pH of the body's internal environment and
pH paper help you to maintain good healthy body by testing many usual substances,
including moisturized soap, lemon juice, milk, liquid detergent,
moisturized soil, saliva, urine, sweat, etc
