Is HBrO4 a weak acid?
Perbromic acid is a strong acid and strongly oxidizing. It is the most unstable of the halogen(VII) oxoacids. It decomposes rapidly on standing to bromic acid and oxygen.
Which is stronger acid HClO4 or HIO4?
The Hydrogen atom in HClO4 will experience less attraction to Oxygen than in HIO4 (the electron is further). That’s why HClO4 is stronger than HIO4.
Is HBrO4 a strong acid?
The pKa of HBrO3 is -2 and of HBr04 is -4.6. This means that both are strong acids, completely ionized in water. HBrO4 is a stronger acid than HBrO3 by over 2 orders of magnitude.
Which is stronger HBrO2 or HBrO4?
Ernest Z. HBrO2 is the stronger acid.
What is the name of NaBrO3?
Sodium bromate
Sodium bromate | NaBrO3 – PubChem.
Is hbro3 an acid or a base?
Bromic acid, also known as hydrogen bromate, is an oxoacid with the molecular formula HBrO3. It only exists in aqueous solution. It is a colorless solution that turns yellow at room temperature as it decomposes to bromine….Bromic acid.

Which is the stronger acid HIO4 or hihbro4?
HBrO4 is the stronger acid. All things being equal HIo4 would be strongest because iodine is more electronegative and the setup for the structure has it connected to an oxygen connected to a hydrogen. the iodine will pull some of the electronegativity from the oxygen making it less able to hold onto the hydrogen ion.
Why is HClO4 the strongest acid in the series?
As another answer pointed out, HClO4 is the strongest acid in the series because the negative charge on the conjugate base (ClO 4 −) is resonance-stabilized over all four oxygens. Why do you combine acid strength and oxidizer strength into a single property as if they are destined to be the same? They are not.
What is the difference between H-Br and H-I bond strength?
It is about the strength of the H-Br versus H-I bond. Since I is larger than Br, the H-I bond is longer, weaker, and therefore more prone to dissociation. See here for more in-depth discussion. The H-O bond is approximately of equal strength in both acids and therefore you turn to electronegativity arguments.
Is H B R O x 4 stronger than H I O X4?
But then, I read somewhere that H B r O X 4 is stronger than H I O X 4, because in this case it’s electronegativity that plays the important role. How do you know whether to use size or EN as a guideline for comparing strengths of acids/bases?
