Question

Write the chemical equation for hbro reacting with water. what are the products? do you expect to have any hbro molecules left in solution when the reaction is completed/reaches equilibrium?

Answer 1

1) HOBr stands for hypobromous acid. On reacting with water, products formed are OBr- and H3O+. Following reaction occurs during this process.

                                     HOBr + H2O ⇄ OBr- + H3O+

2) HOBr is a weak acid and have a lower value of dissociation constant (Ka ~ 2.3 X 10^–9). Hence,  large number of undissociated HOBr molecules are left in solution, when the reaction is completed/reaches equilibrium.

Answer 2

Answer:

1. Reaction:

$HBrO+H_2O-->H_3O^{+}+BrO^{-}$

2. Yes, the solution will have HBrO molecules.

Explanation:

Hello,

In this case, the undergoing chemical reaction involving hypobromous acid and water yields both hypobromite and hydronium ions as shown below:

$HBrO+H_2O-->H_3O^{+}+BrO^{-}$

Now, since hypobromous acid's pKa is about 2x10⁻⁹, such value indicates that it is not completely dissociated in this reaction, therefore, there will be an amount of hypobromous acid molecules even when the equilibrium is attained.

Best regards.
