The lower the pKa, the more acidic the acid is, and the more it likes to donate H+ ions. The most important factor determining how much a particular acid ionises and falls apart is the pH of the solution it’s in. It just so happens that when the pH is equal to the pKa, it’...
have not seen an extensive study on this, from my experience, the most common reasons are that the wines are too "acidic," "sour" and "tart," and that Champagne makes drinkers more easily intoxicated and/or flushed. In addition, some cite the cold temperature as a reason for opting out...

What does acidification mean in chemistry? Introduction. Acidification isa natural process by which the content of the soil becomes more acidic. This happens through the loss of basic/alkalic elements like calcium, magnesium, and potassium and/or the introduction of acidic elements like hydrogen and...
Why is water a good solvent and what determines how acidic a substance actually is? What are the effects of omitting heat on acid-fast staining? Describe three ways that soil pH influences plant growth. What kinds of effects might the altered intracellular calcium level have on the...
The sulfuric acid, in addition to removing the alcohol from the air, also might provide the acidic condition needed for this reaction. During this reaction, the reddish-orange dichromate ion changes color to the green chromium ion when it reacts with the alcohol; the degree of the color ...
expecting the compound to slow tangle accumulation may be more realistic. When calculating sample sizes, especially for clinical endpoints one should consider a) that even if a compound halts the disease in its tracks, an improvement above baseline is not to be expected with disease-modifying ...

[9]. In a more recent study, no difference in chromatin integrity as assessed using the sperm chromatin structure assay (SCSA) was found in post-pubertal bulls with mean ages of 13, 18, and 24 months [10]. However, currently, animals with reproductive potential are selected from even ...
