Briefly, the washed hair was digested in an alkaline solution, complexed by cysteine, urea, and cupric ion, then acidified with sulfuric acid. |
|
A reducing sugar, like lactose, is one which will chemically reduce the blue cupric ions of Benedict's solution to cuprous ions. |
|
One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate. |
|
True verdigris is actually a coating of cupric carbonate formed by weathering on copper, brass and bronze from age. |
|
These reactions depend on the ability of the reducing sugar to convert cupric sulfate to cuprous oxide with a resulting color change. |
|
Fibroin is partly soluble in concentrated solutions of lithium thiocyanate or in mixtures of cupric salts and ethylene diamine. |
|
The oxidizing fluxes usually include cupric oxide or manganese dioxide, which decompose at copper alloy melting temperatures to generate the oxygen required. |
|
Palladium chloride is employed industrially in the catalytic oxidation of ethylene to acetaldehyde in the presence of cupric chloride. |
|
In the manufacture of printed circuit boards, the unwanted copper is etched away by acid solutions of cupric chloride. |
|
The toxicity of copper to aquatic animals depends on the amount of bioavailable cupric ion in the water. |
|
A method of controlling disease damage to a crop plant, which method comprises applying to the plant a composition comprising cupric gluconate. |
|
All copper concentrations are expressed in the risk assessments as the copper or cupric ion, the toxic ion of concern. |
|
An additional four pesticides have only antimicrobial uses: copper naphthenate, copper 8-quinolinolate, metallic copper powder and cupric oxide. |
|
Copper oxychloride, cupric hydroxide and Bordeaux mixture are used to control a range of fungus diseases including mildews, anthracnose and leaf spots. |
|
Copper-containing pesticides are formulated using various forms of copper, which ultimately dissociates into the cupric ion, the active component. |
|
Alternatively, addition of cupric sulfate gives cuprous iodide. |
|
Once graced by Ernest Hemingway and William Carlos Williams, it is now tragically blighted by wide-screen TVs, but still serves the best and tartest margaritas on the planet, little cupric charges of lucidity. |
|
The palladium is presumed to be repeatedly converted from the salt to the free metal, the function of the cupric chloride being to participate in the re-formation of the palladium salt from the metal. |
|
In 1871 an industrial process was developed for the oxidation of hydrochloric acid to chlorine in the presence of cupric salts impregnated in clay brick. |
|
The cupric nickel rotor had a light cover of corrosion products. |
|
|
Incompatibility with other substances: Emits toxic cyanides fumes when heated to decomposition, or on contact with acid or acid fumes. Incompatible with ammonia, chromic anhydride, cupric nitrate, sodium nitrate. |
|
Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. |
|
Table 2 shows the effects of dietary cupric sulfate and cupric methionate on growth performance in growing pigs. |
|
Nelson showed that under laboratory conditions, cupric oxide nanoparticles have the capacity to enter plant root cells and generate many mutagenic DNA base lesions. |
|
This is a problem because cupric oxide is an oxidizing agent. |
|
The most commonly used etchants by flexible circuit manufacturers are cupric chloride, ferric chloride, and to a lesser extent some ammoniacal etchants. |
