| Both the chromate and the bichromate of potassium are extensively used in dyeing and calico-printing. |
| A solution of pigment, gum arabic and potassium bichromate is coated on paper and dried. |
| When hydrochloric acid is added to bichromate of potash, chromic acid is liberated. |
| You can change the color of the image by toning or applying gum bichromate emulsions to a finished platinum print. |
| A piece of carbon paper is then coated lightly with gelatine, sensitized with bichromate of potassium and allowed to dry. |
| The glycerine may also be determined by the acetin or bichromate methods after driving off the alcohol and ether if so desired. |
