If we dump hydrochloric acid onto the entire volume of nitric acid at once—all these nasty products are liberated immediately and potentially explosively. If instead, we slowly add the nitric acid to the hydrochloric acid, the reaction proceeds gently. Excess heat is allowed to dissipate, and t...
from Chapter 13 / Lesson 2 62K Learn the dilute and concentrated solution definition. Compare and contrast dilute vs concentrated solution examples and see how a solution changes physically and chemically as it goes from dilute to concentrate. Related...
The real issue is with sulfuric acid, not that I would dilute conc. nitric nor conc. hydrochloric acids. Its just that sulfuric acid generates much more heat, and so much dense than water, a few drops of water would skitter about on the sulfuric acid surface, and sulfuric acid's viscosit...
Unrelenting indigestion may be caused by a lack of hydrochloric acid or not enough digestive enzymes when eating liquid with foods which dilutes the juices in our stomach. What the first thing a waitress or waiter asks you when you sit down in a restaurant? “What can I bring you to drin...
However, as with all toxic chemicals, it's important to follow safety guidelines, dilute solutions as recommended and avoid mixing with other chemicals, which can produce toxic fumes. Chlorine Bleach vs. Non-chlorine Bleach Not all bleach contains chlorine. Regular bleach, sometimes called laundry...
battery acid and lemon juice. Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic. However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is...

Hydrochloric acid was added as vapour and sulphuric acid as a dilute aqueous solution and the fibres subsequently air-dried. The acid-aged fibres became more digestible to rumen fluid (in vitro) and to cellulase, with improvements up to four-fold (for 1.1% hydrochloric acid in oat hulls). ...
