Frequently Asked Questions

What is the name of the compound HBrO4?

The compound perbromic acid is the inorganic compound with the formula HBrO4. It is an oxoacid of bromine. Perbromic acid is unstable and cannot be formed by displacement of chlorine from perchloric acid, as periodic acid is prepared; it can only be made by protonation of the perbromate ion.

Why is HBrO4 aqueous solution neutral?

And btw: Perbromic acid HBrO4 is a very strong acid… it’s pKa is at about -8! So in return the basicity (pKb) of its conjugated base is VERY weak! So the aqueous solution is neutral. Neither. KBrO4 dissociates into K+, the potassium ion, and BrO4-, perbromate, in water. The BrO4- ion bonds with H+ to form perbromic acid.

What is the ionic bond of bro4-?

The BrO4- ion bonds with H+ to form perbromic acid. While perbromic acid is weak, remember that the K+ in the solution forms KOH, which is a strong base. Therefore the overall solution will be basic.

Is kbro4 a strong acid or a base?

It can be formed from the reaction of an acid and a base. A solution of KBrO4 is neutral since perbromic acid (although an unstable acid) is probably a strong acid, similar to HClO4, (although it’s Ka is hard to find) and potassium hydroxide is a strong base.
