It must be sulfuric acid, the stronger the non-metallic nature of the element, the more acidic it is that the hydrate corresponding to the most ** oxide (that is, the most ** oxygenated acid) will be.
-
Selenic acid, sulfuric acid, sulfurous acid, hydrosulfuric acid.
Selenic acid is basically an inorganic acid second only to perchloric acid.
-
Hello! But selenic acid is stronger than sulfuric acid.
Mine, are you still satisfied?
-
dAcidity from strong to should be DBCA

Answer]: Chunqing c
NH3 is a weak base, alkaline, according to the position of V, scattering N, and Si in the periodic table, the acidic order is HN03>H2Si03>HV03, so HN03 has the strongest acidic grip.

The acidity of the lower yard rolling dibasic acid is the strongest.
a.Adipic acid.
b.Malonic acid is absolute.
c.Succinic acid.
d.Glutaric acid.
Correct Answer: a
-
Among the following substances, the most acidic is () sold with reeds.
Correct Answer: D
-
Answer]: Ac, D are not acidic, and the electron-absorbing ability of methyl groups is stronger than that of hydrogen atoms, so formic acid is more acidic than acetic acid.
-
You can take reverse thinking to judge, the weakest alkaline, the most acidic. The alkalinity is then judged according to the metallicity, and B has the greatest electronegativity and the weakest alkalinity. So choose A
-
1.Carbonic acid. 2.Nitric acid.
Correct Answer: Carbonic acid.
Nitric acid belongs to Zhengdong stove in the category of strong acid, while carbonic acid belongs to the class of weak acid, and the acidity of carbonic acid is weaker than nitric acid.
-
The factors that affect the strength of the acidic chain are ().
a.The structure of matter.
b.Temperature nucleus finches.
c.Solvent. d.Pressure.
Correct Answer: a
-
The acidity of b carboxylic acid depends on the stability of the acid ions. Since the acid ion has a negative charge of 1 unit, all groups that can disperse this negative charge (electron withdrawing group) will enhance the stability of the acid ion, which in turn will enhance the acidity of the carboxylic acid.
In a and c, -H and -CH3 are both electron-donor groups, which will increase the charge of the acid group and reduce the acidity.
In B and D, although there is electron-withdrawing -Cooh, there is a -CH2- in the interval between the two coohs of D, which greatly reduces the electron-withdrawing ability of the second -CoOH (the induction effect decreases greatly with the increase of distance), so the acidity of D is not as strong as that of B.
The general formula of oxygenated acid can be written r-o-h like this, the easier it is to lose h, the more acidic it is. It depends on the force of the r-o side on h. The above three acids are the substitution of acetic acid in the two positions, only F, Cl and H are not the same, F and Cl have a certain electron withdrawing effect, but the F radius is smaller than Cl, and the electron withdrawing effect is larger than Cl, so the electrons are biased towards the R group, which reduces the electron cloud density on O, so that H is easier to remove, so the acid replaced by F is more acidic. >>>More
