Sulfites used in food processing (but not as a preservative) are required to be listed if they are not incidental additives (21 CFR 101.100(a)(3)), and if there are more than 10 ppm in the finished product (21 CFR 101.100(a)(4)) On July 8, 1986, sodium bisulfite (and other sulfites : "The chemicals affected by the order are sulfur dioxide ...
While men are less likely to develop osteoporosis, it is possible and has been occurring more often in recent years in men over age 65. “Most men should aim for 1,000 - 1,200mg of calcium per ...
It can cause a black tongue and black stools in some users of the drug when it combines with trace amounts of sulfur in saliva and the colon to form bismuth sulfide. [7] Bismuth sulfide is a highly insoluble black salt, and the discoloration seen is temporary and harmless. Long-term use (more than six weeks) may lead to accumulation and ...
It comes in yellow flakes and has been used in traditional and alternative medicine for humans and animals, as well as in alchemy and sulfuring fruit before drying. Purified sulfur (sulfur depuratum) is prepared by washing sublimed sulfur with ammonia. It is a fine yellow powder. It was formerly used as a laxative, but this application is rare ...
breathing difficulty with low blood oxygen, potentially related to sulfite-containing compounded drugs. It also said sulfites may cause severe allergic reactions and life-threatening or less ...
Another use of bisulfite in organic chemistry is as a mild reducing agent, for example to remove traces or excess amounts of chlorine, bromine, iodine, hypochlorite salts, osmate esters, chromium trioxide and potassium permanganate. Sodium bisulfite is a decoloration agent in purification procedures because it reduces strongly coloured ...
Ultrafiltration can also be used to separate lignosulfonates from the spent pulping liquid. [1] A list of CAS numbers for the various metal salts of lignosulfonate is available. [4] The electrophilic carbocations produced during ether cleavage react with bisulfite ions (HSO 3 −) to give sulfonates. R-O-R' + H + → R + + R'OH R + + HSO 3 − ...
Bisulfide (or bisulphide in British English) is an inorganic anion with the chemical formula HS − (also written as SH −).It contributes no color to bisulfide salts, and its salts may have a distinctive putrid smell.
