Soda, calcined

Further important auxiliary agents for the manufacture of soap are caustic soda solution, calcined soda, sodium chloride, and (for the manufacture of soft soap) caustic pottash solution, potassium carbonate, and potassium chloride.

Write the formulas of the substances called soda crystals (washing soda), calcined soda, baking soda, and caustic soda. 

The electrolysis is best performed as follows A solution of 13-15 g. calcined soda and 10 g. potassium iodide in 100 cc. water and 20 cc. alcohol is placed in a porous earthenware cylinder with platinum anode. The cathode, of nickel, is surrounded by a strong solution of sodium hydroxide. The electrolysis is carried out at a temperature of 70° C., with a current density at the anode of 1 amp. per 100 sq. cm., and is continued for 2-3 hours. After several hours the iodoform crystallizes out, the current yield being from 60-70 per cent. The chief by-product remaining in the mother liquor is sodium iodate. 

This behavior permits the discarding of the earthenware cylinder. It suffices to envelop the cathodes with parchment paper, whereby the resistance and the consumption of electrical energy is considerably diminished. The diffusion of the free alkali hydroxide away from the cathode necessitates the continuous introduction of carbonic-acid gas, because caustic alkali prevents the formation of iodoform, while carbonate promotes it. When using the covered cathodes, 20 g. calcined soda, 20 g. potassium iodide, and 50 cc. alcohol in 200 cc. water are electrolyzed at a temperature of 50°-70° a current of carbonic-acid gas being conducted into the solution between anode and...

Davis s Process,—Another method of blending Mer s earth and other substances wi soap, is that proposed by Hr, Davis, in which pipe-clay, pearlash, or calcined soda, are introduced. When pearlash, or soda, is employed it is first calcined and then ground up with the Mer s earth and clay until intimately mixed, and in this condition they are to be incorporated with the soap. The proportions are— To every 136 lbs. of soap, in a melted state, take 50 lbs. of fuller s earth, slaked or dried, 56 lbs. of dried pipe-clay, and 112 lbs. of calcined soda or pearlash, all in powder, and sifted as finely as possible. Incorporate the whole by stiiimg or oiutcbing, as quickly as possible before the pasty mass cools. If it is desirable to omit the fuller s earth in the above formula, the proportions are to be —soap, 120 lbs. dried pipe-clay, ll2 lbs. and calcined alkali, 96 lbs. This soap is said to... 

Due to the higher concentrations of Ca and Mg in those solar pond brines, brine purification (easing the task to achieve product purity) cannot be considered. The high consumptions of soda ash, calcined soda, and calcium chloride (or lime milk and hydrochloric acid), and the disposal costs for the filter cakes including the additional investment costs caimot reach feasibility. In this case and for this concept.
