Dear teachers/seniors, I’m sorry to ask, but what does meq/g mean? . . It can’t be found in the book. Original text: (mL NaOH) (0.01N NaOH) = meq/g TACD 10 g sample PS: What does TACD mean?
“\"Ion exchange capacity\" refers to the number of milliequivalents of ions that can be exchanged per gram of dry resin or per milliliter of wet resin, expressed as meq/g (dry) or meq/mL (wet); When the ion is monovalent, the number of milliequivalents is equal to the number of millimoles (for divalent or polyvalent ions, the former is the latter multiplied by the valence of the ion).
meq/g, milliequivalents per gram. A meq is a concept related to the amount of substance; the number of equivalents is equal to the number of moles divided by the valence number of the substance, while the number of milliequivalents is one thousandth of the number of equivalents. It is commonly used in contexts such as adsorption capacity, solubility, and effective content; for example, in terms of adsorption capacity, it indicates how many milliequivalents of a substance can be adsorbed by 1 gram of the adsorbent. It is not necessarily only used for the \"ion exchange capacity\" mentioned above”
I understand. Thank you to loumadadi116 on floor 3. I hadn’t used the equivalent value for a long time and had forgotten about it. The original text was sent by an American client; it contains the calculation formulas.
