| The two listed active ingredients, white bryony and potassium dichromate, are diluted to.000001 PPM and 1 PPM respectively. |
|
| This can be carried out using chemical oxidation agents such as hydrogen peroxide, ozone, or potassium dichromate. |
|
| Common oxidants include the halogens, oxygen, ozone, potassium permanganate, potassium dichromate, nitric acid, and concentrated sulfuric acid. |
|
| Ethanol can be chemically oxidized using a mixture of concentrated sulfuric acid and sodium dichromate. |
|
| The breath sample is bubbled in one vial through a mixture of sulfuric acid, potassium dichromate, silver nitrate and water. |
|
| He had very bad luck with the permanganate bleach and recommends the dichromate bleach instead. |
|
| Most chromium chemicals are produced from sodium dichromate, which is manufactured directly from chemical-grade chromite. |
|
| In all but one of the incidents, Ms Haynes avoided harm: the bright-orange potassium dichromate and the arsenic compound were easy to spot. |
|
| In this technique nervous tissue is fixed with potassium dichromate and then suffused with silver nitrate. |
|
| She has also worked in platinum, gum dichromate, and encaustics. |
|
| The most regularly employed oxidizing agent for this set of reactions is a mixture called chromic acid, a mixture of sodium or potassium dichromate and sulfuric acid. |
|
| Potassium hydroxide would cause an orange coloured potassium dichromate solution to change to yellow. |
|
| Potassium dichromate can also be used as a reference substance for green algae. |
|
| Oxidation by washing with cold water or treatment with oxygenated water or potassium dichromate and sulphuric acid. |
|
| The equilibrium is disturbed once again, and the chromate ions react with the hydrogen ions to form dichromate ions. |
|
| This solution more or less corresponds to half its volume of dichromate solution when just prepared. |
|
| Propose a reason why adding sodium hydroxide to the solution of potassium dichromate caused a colour change. |
|
| Potassium dichromate is an oxidizer and therefore presents a fire hazard. |
|
| This reagent is produced by heating the ore with soda ash and then leaching out soluble chromate, which is then converted to the dichromate by treatment with sulfuric acid. |
|
| Organic matter content of the soils was determined using the dichromate method. |
|
|
|
| The positioner housing is constructed from durable die-cast aluminum and treated with a dichromate undercoat and polyester powder top coat for protection against the toughest applications in all process industries. |
|
| Perkin's accidental discovery of mauve as a product of dichromate oxidation of impure aniline motivated chemists to examine oxidations of aniline with an array of reagents. |
|
| Four substances were put forward as emergent substitute products to potassium permanganate: sodium dichromate, mono potassium persulphate, ozone and hydrogen peroxide. |
|
| The dichromate is then reduced with carbon to chromium sesquioxide, Cr2O3, and that oxide in turn is reduced with aluminum to give the chromium metal. |
|
| Among them are sodium chromate, Na2CrO4, and sodium dichromate, Na2Cr2O7, which are used in leather tanning, in metal surface treatment, and as catalysts in various industrial processes. |
|
| This is a multi-process finish of electro-plated zinc, followed by gold colored zinc dichromate to give excellent corrosion resistance and a superior paint base. |
|
| What is the colour of solid potassium dichromate? |
|
| In June 2009, ECHA recommended a selection of 7 substances which it proposes to the European Commission to submit to the authorization procedure as a matter of priority, including DEHP but not sodium dichromate. |
|
| Vowing revenge, Bond, a laboratory technician, stole the chemical 10-chloro-10H phenoxarsine from the company where she worked and purchased potassium dichromate on Amazon. |
|
| The Eaglescliffe site, which now employs around 118, ended production of chromic acid and chrome sulphate, and concentrates on chrome oxide and sodium dichromate. |
|
| To maintain the saturated solution, add more of the distilled water or Ammonium Dichromate, always ensuring that a fine slurry of crystals is present on the bottom. |
