Homework Problem J. 17

Postby Aprice_1J » Tue Dec 03, 2019 10:55 pm

For this problem it asks to identify what the reaction is and what the acid or base is for either the cation or anion. How am I supposed to determine what the cation or anion is? For example on of the compounds that reacts is KClO and water is present, how am I supposed to know to just use ClO?

K+ does not influence pH since it is the conjugate base of a strong base (it is highly stable and doesn't need to take a proton).

By process of elimination, ClO- is the conjugate acid of a weak base. Thus, it is able to accept a proton.

The same question asks you to use either the cation or anion, whichever is a weak acid or weak base in water. How do we determine which is weak in water?
