J.17

Postby Carla Bruebach 1C » Wed Dec 01, 2021 1:49 pm

Can someone explain this problem?

J.17 In each of the following salts, either the cation or the anion is a weak acid or a weak base in water. Write the chemical equation for the proton transfer reaction of this cation or anion with water:
(a) NaC6H5O
(b) KClO
(c) C5H5NCl
(d) NH4Br

*I'm especially confused on why (b) left Cl out of the answer question but (c) did not. Thanks so much!

In part b), the Cl molecule is a part of a compound ion in solution when the H is removed, so it is able to impact pH of the solution. This is why it is relevant in the reaction.

In part c), the Cl- is a stand alone anion when separated from the rest of its compound. Because Cl- does not affect the pH of solution, it is not necessary to include it in the chemical equation.
