Answer

Explanation:

Step1: Identify solution type

$HNO_3$ is a strong acid, which dissociates completely in water to release $H^+$ ions, resulting in a low - pH solution. A typical pH for a dilute solution of a strong acid is around 1 - 3.

Step2: Analyze $NaCl$ solution

$NaCl$ is a salt formed from the reaction of a strong acid ($HCl$) and a strong base ($NaOH$). In water, it dissociates into $Na^+$ and $Cl^-$ ions and does not affect the $H^+$ or $OH^-$ ion concentrations significantly. So, its aqueous solution is neutral with a pH of 7.

Step3: Analyze $NaOH$ solution

$NaOH$ is a strong base, which dissociates completely in water to release $OH^-$ ions. This increases the $OH^-$ concentration and decreases the $H^+$ concentration, resulting in a high - pH solution. A typical pH for a dilute solution of a strong base is around 11 - 13.

Answer:

Aqueous solution of $HNO_3$: pH < 7 (e.g., 1 - 3) Aqueous solution of $NaCl$: pH = 7 Aqueous solution of $NaOH$: pH > 7 (e.g., 11 - 13)
