what is the formula for nitric acid? hno₃ h₃n hno hno₂

Answer

Brief Explanations:

Nitric acid is a strong acid. In nitric acid, the nitrate ion ($\ce{NO_3^-}$) combines with a hydrogen ion ($\ce{H^+}$). According to the rule of writing acid formulas (hydrogen ion + acid - radical ion), the formula of nitric acid is $\ce{HNO_3}$. $\ce{H_3N}$ is ammonia, $\ce{HNO}$ is not a common stable acid - related formula, and $\ce{HNO_2}$ is nitrous acid.

Answer:

$\ce{HNO_3}$
