For example, the hydrated form of sodium sulfide, nominally with the formula Na 2 S · 9 H 2 O, is better described as NaSH · NaOH · 8 H 2 O. The UV–visible spectrum of septic sewage from three different sites. The absorption of bisulfide is observed around 230 nm in each case.
In this technique, sodium bisulfite deaminates cytosine into uracil, but does not affect 5-methylcytosine, a methylated form of cytosine with a methyl group attached to carbon 5. When the bisulfite-treated DNA is amplified via polymerase chain reaction , the uracil is amplified as thymine and the methylated cytosines are amplified as cytosine.

A calcium bisulfite liquor solution is used in the process of converting dihydroquercetin in tree bark pulp and then converting dihydroquercetin to a usable form: quercetin. Calcium bisulfite is not the optimum bisulfite compound for this reaction since the calcium ions can be removed from the calcium bisulfite solution during the reaction ...
It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide. Regardless of its ill-defined nature, sodium bisulfite is used in many different industries such as a food additive with E number E222 in the food industry, a reducing agent in the cosmetic industry, and a decomposer of residual hypochlorite used in the ...

New York's Cardinal Timothy Dolan turns 75 Thursday, and is required to submit his resignation to the Vatican. The formality starts the clock on a time of transition for the Archdiocese of New York.
Between pH 1.2 and 1.8, further hydrolysis occurs and Bi 6 O 5 (OH) 3 (NO 3) 5 ·3H 2 O is formed. The final oxynitrate product of thermal dehydration is believed to be Bi 5 O 7 NO 3, [14] which is isostructural with β–Bi 5 O 7 I and has a layer structure. [17] The ultimate stage of thermal decomposition of oxynitrates is bismuth(III) oxide ...
