**Titration of Nitric Acid by Potassium Hydroxide: pH Determination**Determine the pH during the titration of 14.9 mL of 0.149 M nitric acid by \(7.12 \times 10^{-2}\) M potassium hydroxide at the following points:1. Before the addition of any potassium hydroxide: ____2. After the addition of 15.6 mL of potassium hydroxide: ____3. At the equivalence point: ____4. After adding 38.4 mL of potassium hydroxide: ____**Explanation:**This exercise involves a titration process, where a solution of known concentration (titrant) is used to determine the concentration of an unknown solution. Here, potassium hydroxide (KOH) is the titrant added to nitric acid (HNO₃), a strong acid, to determine various pH levels during the chemical reaction. The reaction leads to the formation of water and potassium nitrate (KNO₃).
