| Potassium dichromate is an oxidizer and therefore presents a fire hazard. |
| Potassium hydroxide would cause an orange coloured potassium dichromate solution to change to yellow. |
| In all but one of the incidents, Ms Haynes avoided harm: the bright-orange potassium dichromate and the arsenic compound were easy to spot. |
| 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. |
| Ethanol can be chemically oxidized using a mixture of concentrated sulfuric acid and sodium dichromate. |
