As above, sodium hydroxide reacts with weak acids such as hydrogen sulfide and mercaptans to give the non-volatile sodium salts which can be removed. The waste which is 在同一产业,品质差原油在过程中可以对待与氢氧化钠去除硫磺杂质以刻薄洗涤物著名。 以上,氢氧化钠起反应与微弱的酸例如氢化硫和...

aThe determination of hydrochloric acid in gastric juice by titration to a fixed potentiometric endpoint is incorrect on a theoretical basis, because of the presence of weak acids and their salts in gastric juice [1]. Moore and Scarlata [2,3]proposed a method by which the hydrogen-ion concentr...
Vbase= volume of the base This equation works for acid/base reactions where the mole ratio between acid and base is 1:1. If the ratio were different, as in Ca(OH)2and HCl, the ratio would be 1 mole acid to 2moles base. The equation would now be: ...
What is an example of a weak base that starts with the letter n and is 7 letters long? Explain how to identify acids under the Bronsted theory. What is saponification in organic chemistry? Is salt acidic or basic? Describe the following as being a Bronsted acid, base, or both: a) H2...
On the other hand, when a weak base, BOH, dissociates in water, it produces {eq}OH^- {/eq}, the hydroxide ion, and {eq}B^+ {/eq}, the conjugate acid of the weak base. Buffers cannot be created with strong acids or bases because their conjugates do not act as bases or ac...
is used to distinguish strong acids from weak acids. strong acids have exceptionally high ka values. the ka value is found by looking at the equilibrium constant for the dissociation of the acid. the higher the ka, the more the acid dissociates. q5 how do you calculate the ka of water?
You are glad when the fast (禁食) is over and you get your reward of a delicious meat meal. Proteins are built up from about twenty food elements called "amino acids" (氨基酸), which are found in greater amounts in animal protein than in vegetable protein. This means you have to eat...
aNeutralization equivalents of the fractions indicated that only C18 unsaturated acids were present. The high neutralization equivalent of the residue,which was quite small, was assumed to be due to polymerization during distillation. 分数的中立化等值表明C18仅不饱和的酸存在。 残滓的高中立化等值,是...
