The name of $NaHSO_3$ is: "Sodium hydrogen sulfite".

Work Step by Step

1. Identify the positive ion, and name it. $Na^+$ is the positive ion. So, the first name of the compound will be: "Sodium." 2. Identify the negative ion, and name it. $HS{O_3}^-$ is the negative ion. As we can see in Table 2.2 (Page 58), $S{O_3}^{2-}$ is called "sulfite", $S{O_4}^{2-}$ is called "sulfate" and $HS{O_4}^-$ is called "hydrogen sulfate". Using the same logic, $HS{O_3}^-$ is called "hydrogen sulfite". 3. Putting those two names together: $Na^+ + HSO{_3}^- = NaHSO_3$ Sodium + hydrogen sulfite = Sodium hydrogen sulfite.
