Question
fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table. some ionic compounds
cation: na⁺, ba²⁺, nh₄⁺
anion: oh⁻, co₃²⁻, bro₃⁻
empirical formula
name of compound
Step1: Identify cation names
$\text{Na}^+$ is sodium ion, $\text{Ba}^{2 + }$ is barium ion, $\text{NH}_4^+$ is ammonium ion.
Step2: Identify anion names
$\text{OH}^-$ is hydroxide ion, $\text{CO}_3^{2 - }$ is carbonate ion, $\text{BrO}_3^-$ is bromate ion.
Step3: Form empirical formulas
For $\text{Na}^+$ and $\text{OH}^-$, the formula is $\text{NaOH}$ (sodium hydroxide). For $\text{Na}^+$ and $\text{CO}_3^{2 - }$, it is $\text{Na}_2\text{CO}_3$ (sodium carbonate). For $\text{Na}^+$ and $\text{BrO}_3^-$, it is $\text{NaBrO}_3$ (sodium bromate). For $\text{Ba}^{2 + }$ and $\text{OH}^-$, it is $\text{Ba(OH)}_2$ (barium hydroxide). For $\text{Ba}^{2 + }$ and $\text{CO}_3^{2 - }$, it is $\text{BaCO}_3$ (barium carbonate). For $\text{Ba}^{2 + }$ and $\text{BrO}_3^-$, it is $\text{Ba(BrO}_3)_2$ (barium bromate). For $\text{NH}_4^+$ and $\text{OH}^-$, it is $\text{NH}_4\text{OH}$ (ammonium hydroxide). For $\text{NH}_4^+$ and $\text{CO}_3^{2 - }$, it is $(\text{NH}_4)_2\text{CO}_3$ (ammonium carbonate). For $\text{NH}_4^+$ and $\text{BrO}_3^-$, it is $\text{NH}_4\text{BrO}_3$ (ammonium bromate).
