Which of the following is a strong acid HClO4 HBrO4 HIO4 HNO3?
HClO4, perchloric acid, is the stronger acid.
Is HIO4 strong acid?
The first 3 that I’m going to write down are HCL; Hydrochloric acid, HBr; Hydrobromic acid, and HI; Hydroiodic acid. So HNO3, H2SO4, HClO4, and so those 3 are also strong acids. Sometimes Periodic acid HIO4 is considered strong but not commonly.
Why HClO4 is stronger acid than HCL?
In Group 17 oxyacids, electron density is drawn away from the O atom as the electronegativity of the halogen increases. This in turn draws electron density away from the O–H bond and weakens it. The weaker the O–H bond, the stronger the acid.
Which is strongest acid HClO4?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid. The acidic strength of oxoacids of chlorine is in the order ‘HClO4,HClO3,HClO2,HClO’ Briefly explain the reason for this.
Is nabro3 a strong or weak acid?
Sodium bromate, the inorganic compound with the chemical formula of NaBrO3, is the sodium salt of bromic acid. It is a strong oxidant.
Why is HClO4 stronger than HBrO4?
In fact, perchloric acid is usually considered as the strongest of all simple acids. Among oxoacids of elements of the same group having similar composition, acid strength increases as electronegativity increases. Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4.
Which is more acidic HClO4 or H2SO4?
HClO4 is more acidic by around 7 pKa units. HClO4 because central atom (chlorine) is more electronegative than iodine. Besides, periodic acid is highly unstable and in fact has formula: H5IO6. Perchloric acid is one of the strongest mineral acids (stronger than 100\% H2SO4).
What is the difference between pKa of HClO4 and HClO3?
Thanks for the A2A. pKa of HClO4 (-10) is lower than HClO3 (-1). Acids with lower pKa are stronger. Electronegative nature of the O atom—ClO4- has 1 additional O atom which is further able to stabilise the negative charge on the ion.
Which is stronger HIO4 or iodine?
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.
