Litmus Test (chemistry)
Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. It is a purple dye that is extracted from a type of algal bloom called ‘lichens’. In an acidic medium, blue litmus paper turns red, and red litmus paper turns blue in a basic or alkaline medium. History The word "litmus" comes from an Old Norse word for "pulp". About 1300 the Spanish physician Arnaldus de Villa Nova began using litmus to study acids and bases. From the 16th century onwards, the blue dye was extracted from some lichens, especially in the Netherlands. Natural sources Litmus can be found in different species of lichens. The dyes are extracted from such species as ''Roccella tinctoria'' (South American), ''Roccella fuciformis'' (Angola and Madagascar), ''Roccella pygmaea'' (Algeria), ''Roccella phycopsis'', '' Lecanora tartarea'' (Norway, Sweden), ''V ...

Litmus Test (politics)
In politics, a litmus test is a question asked of a potential candidate for high office, the answer to which would determine whether the nominating official would proceed with the appointment or nomination. The expression is a metaphor based on the litmus test in chemistry, in which one is able to test the general acidity of a substance, but not its exact pH. Those who must approve a nominee may also be said to apply a litmus test to determine whether the nominee will receive their vote. In these contexts, the phrase comes up most often with respect to nominations to the judiciary. Usage The metaphor of a litmus test has been used in American politics since the mid-twentieth century. During United States presidential election campaigns, litmus tests the nominees might use are more fervently discussed when vacancies for the U.S. Supreme Court The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States.

Litmus Test Of Medjugorje
Medjugorje ( hr, link=no, Međugorje), a village in the south of Bosnia and Herzegovina, has been the site of alleged apparitions of the Blessed Virgin Mary since 24 June 1981. Various officials of the Catholic Church have attempted to discern the validity of these Marian apparitions in order to provide guidance to potential devotees and pilgrims. On 7 December 2017, it was reported that Archbishop Hoser, Pope Francis' envoy to Medjugorje, announced that official pilgrimages are allowed, stating, "dioceses and other institutions can organize official pilgrimages." This pilgrimage was officially authorized by the Holy See in May 2019. The approval was not intended to signify recognition of the apparitions, but acknowledge the faith and pastoral needs of the pilgrims. Background When Bosnia and Herzegovina became part of Austria-Hungary, Pope Leo XIII took steps to establish dioceses (1881) and appoint local bishops. This included transferring parishes administered until then by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Litmus Test
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...
