What is the strongest acid?
The strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine. As the number of oxygens increases, so does the acid strength; again, this has to do with electronegativity.
What is an oxoacid?
To be more specific, an oxoacid is an acid that: contains oxygen. contains at least one other element. has at least one hydrogen atom bonded to oxygen. forms an ion by the loss of one or more protons in solution. Examples of oxoacids include:
What is the pKa of HOI?
Consider the simple oxyacids HOI (hypoiodous acid), HOBr (hypobromous acid), and HOCl (hypochlorous acid). These acids can be arranged in order of their pKavalues and, by extension, their relative strengths: HOCl pKa = 7.5 < HOBr pKa = 8.6 < HOI pKa = 10.6 Recall that smaller values of pKa correspond to greater acid strength. Therefore, HOCl is the strongest acid and HOI is weakest, and acid strength decreases as the central halogen descends on the periodic table.
Which superacids release protons?
The superacids readily release protons, which is a slightly different criterion for acid strength than the ability to dissociate to release a H+ ion (a proton). The strongest carborane superacid has the chemical structure H (CHB11Cl1).
Why is oxygen called an acid generator?
So, he gave the name oxygen (acid generator) to it after the success of his oxidation theory in explaining the phenomenon of burning or combustion of substances in air, in late 18th century. Later on hydrogen came to be recognized as the universal component of acids. The halogens like chlorine and bromine were discovered only in the 19th century.
Which is stronger, HOCl or HOI?
Therefore, HOCl is the strongest acid and HOI is weakest, and acid strength decreases as the central halogen descends on the periodic table. The strength of the acid is determined by the central atom’s electronegativity relative to the surround atoms in the molecule.
Which type of reagents tend to gain electrons in the reaction?
A more general classification was therefore made by dividing the reagents which take part in acid-base and oxidation-reduction reactions into two types. Electrophilic reagents are those which tend to gain electrons in the reactions considered. Electrodotic reagents are those which tend to lose electrons .
Which acid is the weakest?
HF will be the weakest acid as the polarising ability of fluorine is the highest and bond breaking of HF requires a huge amount of energy..
What is the acidity of oxy acid?
Acidity of Oxy acid (HOCl, HOBr, and HOI) depends on the polarity of the bond. In all three oxy acid, same atom O is attached to H in all acids. Here, Electronegativity of atom X (F, Cl or Br or I) attached to O decreases down a group, polarity of OH bond decreases, acid strength decreases. It means more the electronegativity ...
Why is HoI a strong acid?
HoI is the strong acid because the acidic nature of the acid depends on the electronegativity of the atom. And down the group the electronegativity decreases. As electronegativity decreases the acidic nature of the acid increase. In this the the electronegativity is in the order given is ofluorine >chlorine >bromine >iodine.
What happens when the central chlorine atom is attached to the electron withdrawing oxygen atom/s?
The more the electron withdrawing oxygen atoms, more will be the electron withdrawing effect. Once the electron on the bonded hydrogen atom is pulled towards the oxygen atom, the hydrogen atom can be removed as hydrogen ion. If more oxygen atoms are present, then the combined withdrawal effect makes it easier for the formation of hydrogen ion. Hence electron withdrawal increases strength of the acid.
How is acid nature determined?
The acid nature is determined by the ease of donating Hydrogen atom so according to this concept the order of decreasing acid nature of substance is
