Bromine monofluoride is a quite unstable interhalogen compound with the chemical formula BrF. It can be produced through the reaction of bromine trifluoride (or bromine pentafluoride) and bromine. Due to its lability, the compound can be detected but not isolated: [2] BrF 3 + Br 2 → 3 BrF BrF 5 + 2 Br 2 → 5 BrF Br 2(l) + F 2(g) → 2 BrF (g)
Chlorine monofluoride (ClF) is the lightest interhalogen compound. ClF is a colorless gas with a normal boiling point of −100 °C. Bromine monofluoride (BrF) has not been obtained as a pure compound — it dissociates into the trifluoride and free bromine. It is created according to the following equation: Br 2 (l) + F 2 (g) → 2 BrF(g)
Carbon monofluoride (CF, CF x, or (CF) x), also called polycarbon monofluoride; Chlorine monofluoride, a volatile interhalogen compound with formula ClF; Iodine monofluoride, a chocolate-brown solid compound with formula IF; Hydrogen fluoride, a liquid or gas with boiling point at about 20 °C, HF; Nitrogen monofluoride, a metastable compound ...
While chlorine and bromine heptafluorides are not known, the corresponding cations ClF + 6 and BrF + 6, extremely strong oxidizers, are. [94] Astatine is not well-studied, and although there is a report of a non-volatile astatine monofluoride, [95] its existence is debated. [96] Many of the halogen fluorides are powerful fluorinators.
Bromine fluoride may refer to several compounds with the elements bromine and fluorine: Bromine monofluoride, BrF;
Chlorine trifluoride, whose corrosive potential ignites asbestos, concrete, sand and other fire retardants [133] Binary fluorides of metalloids and p-block nonmetals are generally covalent and volatile, with varying reactivities. Period 3 and heavier nonmetals can form hypervalent fluorides. [134]
Lime comes from Old English lim ('sticky substance, birdlime, mortar, cement, gluten'), and is related to Latin limus ('slime, mud, mire'), and linere ('to smear'). [7] Mortar is a mixture with cement and comes from Old French mortier ('builder's mortar, plaster; bowl for mixing') in the late 13th century and Latin mortarium ('mortar'). [7]
Concrete carbonation can be visually revealed by applying a phenolphthalein solution over the fresh surface of a concrete samples (concrete core, prism, freshly fractured bar). Phenolphthalein is a pH indicator , whose color turns from colorless at pH < 8.5 to pink-fuchsia at pH > 9.5.
