Lead chromate 13 Neutralization

Lead chromate is found naturally in minerals crocoite and phoenicochroite. It also is readily prepared by adding a soluble chromate such as sodium or potassium chromate to a solution of lead nitrate, lead acetate or other soluble lead(II) salt in neutral or slightly acidic solution ... [Pg.465]

Synftiesis is by adding a neutral solution of a soluble lead salt (acetate or nitrate) to an alkali (usually potassium or sodium) chromate or dichromate solution (Beam, 1923) Kittel (1960) states that chrome yellow may also be made directly by adding lead monoxide to chromates in paste form. From the work of Vauquelin (1809), Kuhn and Curran suggest that lead chromate was introduced as a pigment between 1804 and 1809. [Pg.99]

Bichromate of Lead—2 PbO, CrOj— chrome red— may bo obtained by boiling oxide of lead, or its car-bonato, with on aqueous solution of monochromate of potassa, or by digesting the neutral chromate of lead in a dilute solution of caustic potassa. Liebig prepared it by adding a neutral ebromate to fased nitre, and washing the residuum it is an insoluble, scarlet colored powder. [Pg.1205]

Gravimetric Methods.—The vanadium compound is converted into sodium vanadate by fusion or other method, and after separation from other salts (e.g. arsenate, molybdate, phosphate, chromate, tungstate) is precipitated from nearly neutral solution either as (a) mercurous vanadate or (b) basic lead vanadate. In (a), mercurous... [Pg.114]

Titration of the products formed by the interactions of chromium(VI) and molybdenum(VI) oxide with KN03 runs in one stage and leads to the formation of neutral chromates and molybdates, respectively. The investigators calculated the constants of oxide ion addition to Cr207 and Mo30 q according to the following reactions ... [Pg.55]

Figure 4.4 An aqueous ionic reaction and its equations. When silver nitrate and sodium chromate solutions are mixed, a reaction occurs that forms solid silver chromate and a solution of sodium nitrate. The photos present the macroscopic view of the reaction, the view the chemist sees in the lab. The blow-up arrows lead to an atomic-scale view, a representation of the chemist s mental picture of the reactants and products. (The pale ions are spectator ions, present for electrical neutrality, but not involved in the reaction.) Three equations represent the reaction in symbols. (The ions that are reacting are shown in red type.) The molecular equation shows all substances intact. The total Ionic equation shows all soluble substances as separate, solvated ions. The net Ionic equation eliminates the spectator ions to show only the reacting species. Figure 4.4 An aqueous ionic reaction and its equations.

These salts are yellow, orange, or red, the latter colour predominating when the acid is in excess, except in the case of dichromate of lead, which is red. The soluble chromates are recognised by their colour, which is changed to green when alcohol and hydrochloric acid are added, and the mixture is boiled. The general formula for neutral chromates is MO, Cr O3 and for bichromates, MO, 2 Cr O3. [Pg.233]
