An older nomenclature system, still in use to some extent, uses the word acid to denote an acid salt. Also, the prefix bi- may be used for an acid salt of an acid with two ionizable hydrogen atoms. Thus, NaHCOs can be called sodium bicarbonate or sodium acid carbonate instead of sodium hydrogen carbonate (Figure 6.5). 

In an older nomenclature system, the word acid was used to denote an acid salt. In another old system, the prefix bi- was used for a half-neutralized acid that originally contained two ionizable hydrogen atoms. Thns, sodium bicarbonate and sodium acid carbonate are other names that have been nsed for NaHC03.

This salt has already been referred to as cream of tartar. It forms rhombic crystals which are only slightly soluble in water. One of its important uses is as a constituent of baking powders. In such powders the other constituent is sodium acid carbonate. It is also used as a mordant in dyeing. 

This salt crystallizes in thick columns with four molecules of water. Its chief use is as a reducing agent. It reduces an ammoniacal silver solution and in this way is used in silvering glass. It is also used as a constituent of Fehling s solution, (p. 332), which is an alkaline copper solution reduced by certain sugars. It acts as a purgative in Seidlitz powders which consist of sodium-potassium tartrate, sodium acid carbonate and free tartaric acid.

Discussion As was recently stated in the experiment on the preparation of boric acid from borax, a compound may be obtained by double decomposition when it is sufficiently insoluble to be precipitated under the conditions of the reaction. Thus sodium acid carbonate, which is much less soluble than sodium chloride, will be precipitated from a saturated solution of sodium chloride upon the addition of ammonium acid carbonate. The ammonium acid carbonate, however, can not be added in solution, since the additional water would serve to keep the sodium acid carbonate also in solution. Therefore carbon dioxide is passed into a saturated solution of sodium chloride which contains ammonia.

PolyNiTSPc films are prepared by potential cycling GC [6], OPG [7], Au [8, 9], or ITO [10] electrodes at a low scan rate in 0.1 M NaOH or in a pH 11 sodium carbonate/sodium acid carbonate buffer containing 1 mM Ni(II)TSPc (or other Ni (II)N4 water-soluble complex). On gold electrodes (Fig. 1) it has been found by EQCM that each cycle provokes both a mass increase (Fig. lb) and a current increase (Fig. la) of the Ni(in)/Ni(II) process (peaks cl and al in Fig. lb) at about...
