Blue Litmus test paper is a foolproof pH test to determine if something is an acid. The Blue Litmus test paper does not come with a color chart as it cannot provide you with a defined pH value. The test paper will turn red if dipped into an acidic solution (pH <7). The test strip will turn red in seconds if dipped into a solution that is an acid, and will remain unchanged if it is a base.
This item comes in 8″ x 10″ sheets, you can use a paper cutter to make your own custom sized strips from this sheet. You can also use these to monitor manufacturing processes, leak detection of acidic liquids, and scientific testing.
FREQUENTLY ASKED QUESTIONS (FAQ)
What is a litmus test?
A litmus test is a simple experiment or method used to determine the acidity or alkalinity of a substance. It typically involves the use of litmus paper, which changes color when it comes in contact with acidic or basic solutions. A red color indicates acidity (pH < 7), while a blue color indicates alkalinity (pH > 7). Litmus paper is generally qualitative, meaning it will tell you if a solution is acidic or basic. It will not tell you the pH, to measure pH with more precision and quantitatively you need a quantitative pH test. The term “litmus test” is also used metaphorically to describe a quick, decisive way to judge something.
Where does the word “litmus” come from?
The word “litmus” comes from the Old Norse word *litmos*, which means “dye” or “color.” It refers to the dye derived from lichens, particularly those from the genus *Roccella*, which is used in litmus paper to indicate pH levels. This dye is responsible for the color change seen in litmus tests.
