Aweak acid, hf, is in solution with dissolved sodium fluoride, naf. if hcl is added, which ion will react with the extra hydrogen ions from the hcl to keep the ph from changing?
a, oh-
b, na+
c, f-
d, na-
e, none of these

c. F1-

Explanation:

In this chemical reaction the expression is:

HF  +  NaF   →  NaHF2

The ion that always keep the negative charge is the fluorine with a -1, if in this mixture there is more positive ions (H1+) the negative ion (F1-) will join with them.

Remember that also the Cl1- will be free, but the fluorine is more reactive than the fluorine.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
