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

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.

Answer 2

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.
