Litmus papers are often confused with universal pH indicator strips, but the latter is actually a different — and arguably better — technology. Litmus paper has limits to its usefulness. While red litmus paper is effective atdetermining whether a substance is acidic, and vice-versa for blue li...
red litmus paper remains red. In an alkaline solution, red litmus paper turns blue. When an alkaline compound dissolves in water, it produces hydroxide ions, which cause the solution to become alkaline. Red litmus paper can also be used to test...
“Litmus test” being used as a metaphor in American politics is a pretty recent phenomenon (around the mid-20th century). Most commonly it’s used for nominations to the Supreme Court of the United States–politicians do a litmus test on nominees to see whether or not they will give the ...
The litmus paper test is a simple test in order to determine whether a given solution is acidic or basic. After placing a drop of solution on the litmus paper, if it changes a red litmus paper to blue, the solution is basic. If it changes a blue litmus paper to red, the so...

The conjugated base, formed from the litmus acid, has a blue color, so the wet red litmus paper turns blue in alkaline solution. Although the test strips are popular they are not the most accurate measuring device since Liquid pool sets kits are the other main form of testing the water....
