Hydrobromic acid is an aqueous solution of hydrogen bromide.It is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at 124.3 °C (255.7 °F) and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid is one of the strongest mineral acids known.
Hydrogen bromide is the inorganic compound with the formula HBr.It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature.
Addition of bromine to water gives hypobromous acid and hydrobromic acid (HBr(aq)) via a disproportionation reaction.. Br 2 + H 2 O HOBr + HBr. In nature, hypobromous acid is produced by bromoperoxidases, which are enzymes that catalyze the oxidation of bromide with hydrogen peroxide: [2] [3]
The disproportionation reaction of two equivalents hypobromous acid (HBrO) results in the formation of both bromous acid (HBrO 2) and hydrobromic acid (HBr): [citation needed] 2 HBrO → HBrO 2 + HBr. A rearrangement reaction, which results from the syn-proportion of bromic acid (HBrO 3) and hydrobromic acid (HBr) gives bromous acid (HBrO 2 ...
Δ latt H corresponds to U L in the text. The downward arrow "electron affinity" shows the negative quantity –EA F, since EA F is usually defined as positive. For ionic compounds, the standard enthalpy of formation is equivalent to the sum of several terms included in the Born–Haber cycle. For example, the formation of lithium fluoride,

Brianna LaPaglia's Sports Illustrated Swimsuit cover is full-circle.. Last year, Sports Illustrated asked the podcast host, 25, to host the red carpet at the 60th anniversary celebration of the ...
It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water.
