quick question: acidity

which is the strongeest acid:

HOCl HOBr HOI


i know that acidity increases with more oxygens...but how about the above when the # of oxygens are the same?

im dumb for confusing this poor child.

My friend, how's studies? Basiscity decreases as one descends the periodic table, so following that logic, the HOI should be the strongest. If anyone else knows more about this agrees or disagrees, feel free to chime in. Good luck.

thats right. acidity increases from up to bottom but only if it is in the same column in the periodic table.

Acid Strength

HI > HB > HCl >>> HF

Why? Acid strength is most largely determined by the H-X bond energy. Thus, H-I bond is weakest, therefore it is the strongest acid.


HOCl > HOBr > HOI

Why? In this case, the bond energy is the same, an O-H bond in each case. Therefore, electronegativity is the major factor. The more electronegative the halogen, the better the conjugate base is stabilized, therefore, the stronger the acid.


HBrO4 > HBrO3 > HBrO2 > HBrO

In this case, it is similar to above. The more electronegative oxygens, the more stable the conjugate base by induction, the more acidic the conjugate acid.

ahhhhhhh I see it now
