Why is it possible for us to drink a solution that contains a mixture of equal concentration of a strong acid and a strong base, either of which, separately, would be very caustic? Why would it be better to use isotonic sports water? Why does glucose appear in the urine? What is the ...
Acids and alkalis are simply chemicals that dissolve in water to form ions (atoms with too many or too few electrons). An acid dissolves in water to form positively charged hydrogen ions (H+), with a strong acid forming more hydrogen ions than a weak one. An alkali (or base) dissolves...
What are the definitions of acids and bases? Does Hydroiodic acid form ions in water, and what ions does it form? Whar is the name of substances that contain HYDROGEN and produce HYDRONIUM IONS when they dissolve in water? WHAT ION DOES AN ARRHENIUS ACID PRODUCE IN WATER? WHAT ION DOES ...

Basicity. Unlike most amines,indole is not basic: just like pyrrole, the aromatic character of the ring means that the lone pair of electrons on the nitrogen atom is not available for protonation. Strong acids such as hydrochloric acid can, however, protonate indole. ...
In addition, milk-based beverages containing phytosterols have gained a distinct place among these type of functional foods, as phytosterols do not readily dissolve in water based products and so low-fat versions are not as common [235]. Some studies have seen a benefit for the consumption of ...
The sample is treated with acids to dissolve the organic substances. Pollanen, in 1997 [38], was one of the first pioneers who proposed a structured version of this method, taking inspiration from Ludes, 1994 [12], which was later followed by several variants using nitric acid, hydrochloric...
