The name of $KNO_2$ is : "Potassium nitrite"

#### Work Step by Step

1. Identify the positive ion, and name it. $K^+$ is the positive ion. So, the first name of the compound will be: "Potassium." 2. Identify the negative ion, and name it. $N{O_2}^-$ is the negative ion. As we can see in Table 2.2 (Page 58), this ion is called "Nitrite". 3. Putting those two names together: $K^+ + NO{_2}^- = KNO_2$ Potassium + nitrite = Potassium nitrite.
