Can copper sulfate be dehydrated?
COPPER SULFATE PENTAHYDRATE can be dehydrated by heating. Serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292 (1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 (NTP, 1992).

Where is copper absorbed?
Based on studies with radioactive isotopes of copper, most copper is absorbed from the stomach and duodenum of the gastrointestinal tract . Maximum blood copper levels are observed within 1 to 3 hours following oral administration, and about 50 percent of ingested copper was absorbed. Copper absorption is proposed to occur by two mechanisms, one energy- dependent and the other enzymatic. Factors that can interfere with copper absorption include competition for binding sites with zinc, interactions with molybdenum and sulfates, chelation with phytates, and inhibition by ascorbic acid ( vitamin C ). Copper absorbed from the gastrointestinal tract is transported rapidly to blood serum and deposited in the liver bound to metallothionein. From 20 to 60% of the dietary copper is absorbed.
