0 an acid with a pH of between 1 and 3, whose molecules break down into smaller molecules or atoms in water -- 强酸
Ammonium thiocyanate in trifluoroacetic acid and acetic anhydride is added to the peptide, the strong acid protonates the carboxyl group, activating it.
Guanine can be hydrolyzed with strong acid to glycine, ammonia, carbon dioxide, and carbon monoxide.
Thus, it is less capable than a strong acid of donating protons.
A strong acid is one that completely ionizes (dissociates) in a solution.
Reacting metal sulfides with strong acid liberates hydrogen sulfide.
It is the only hydrohalic acid that is not considered a strong acid, i.e. it does not fully ionize in dilute aqueous solutions.
Any acid which is a stronger acid than the ammonium ion will be a strong acid in liquid ammonia.
Chemical burns can be caused by over 25,000 substances, most of which are either a strong base (55%) or a strong acid (26%).
