Writing Ion Formulas

Postby Isabel Nakoud 4D » Mon Dec 03, 2018 11:22 pm

In problem 12.65 part (c),

When writing the aqueous solution of KF, how do we know to write the formula

F- + H2O --> HF + -OH

instead of making the solution about the K+ ion?

It is because F is the one with the negative charge and is able to bind with the H+ atom
