Solution Steps
Step 1: Understanding the Nature of KCl in Solution
Potassium chloride (KCl) is a salt that completely dissociates into its ions, \( \text{K}^+ \) and \( \text{Cl}^- \), in an aqueous solution. Neither of these ions reacts with water to affect the pH, as \( \text{K}^+ \) is a neutral cation and \( \text{Cl}^- \) is a neutral anion.
Step 2: Determining the pH of the Solution
Since KCl does not affect the pH of the solution, the pH of a 1.7 M KCl solution is determined by the pH of pure water, which is neutral.
Step 3: Reporting the pH of the Solution
The pH of pure water at 25°C is 7.00. Therefore, the pH of the 1.7 M KCl solution is also 7.00.
