In the case of diacid and triacid bases, and of dibasic and tribasic acids, the mutual neutralization may vary in degree, producing respectively basic, neutral, or acid salts See Phrases below.
Now in these triacid salts we can remove some of the acid groups and substitute the elements of water, OH, or hydroxyl, as it is called, for them.
Indeed all granules, that are easily soluble, vanish when the triacid method is used, and so a homogeneous cell protoplasm is simulated.
The staining of the blood specimen in triacidrequires only a little fixation, cp.
Their true nature is shown by their behaviour with the triacid solution.
The =triacid solution= was only found after trial of many hundred combinations; and up to the present day this stain in its original form or in slight modifications has played a prominent part in various provinces of histology.
In triacid preparations the granulation is unstained, and the mast cells appear as clear, polynuclear cells, free from granules.
Relatively slight degrees of hardening suffice for staining in simple watery solutions, for example, in the triacid fluid, and can be attained by a short, and not too intense action of several reagents.
The protoplasm possesses no special affinity for acid and neutral dyes, and hence in triacid and hæmatoxylin preparations the small lymphocytes are seen chiefly as lightly stained nuclei, apparently free.
As shewn by the former they appear as polynuclear cells free from granules, since their granulation takes on no dye of the triacid mixture.
They were performed in the following way: dry cover-slip preparations were made from the juice of the glands removed shortly after death, and were stained in the usual way by Ehrlich's triacid mixture.
To obtain a good triacid stain, the preparations may be hardened, according to Nikiforoff, in a mixture of absolute alcohol and ether of equal parts, for two hours.
In the practical application of the triacid fluid, particular care must be taken, as M.
The two granulations always show different shades in the triacid preparation as well; for the nigrosinophil cells stain a blacker hue.
Chemically the above-mentioned example may be thus explained; in this mixture all three basic groups of the methyl green are united with the acid dye, so that we have produced a triacid compound of methyl green.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "triacid" in a variety of sentences. We hope that you will now be able to make sentences using this word.
