### Calculation of Major Species and pH in Acid Solutions

#### Introduction

Understanding the major species present in solutions of acids and calculating their pH is a fundamental concept in chemistry. This exercise focuses on determining the major species in \(0.320 \, M\) solutions of the given acids and calculating their corresponding pH values.

#### Problems:

1. **Phenol (HOC₆H₅) Solution**
   * **Major species:** 
     * (Enter your answer as a comma-separated list.)
     * _______________

   * **pH:** 
     * _______________

2. **Hydrocyanic Acid (HCN) Solution**
   * **Major species:**
     * (Enter your answer as a comma-separated list.)
     * _______________

   * **pH:** 
     * _______________

In this activity, you need to assume a solution concentration of \(0.320 \, M\) for each of the acids and utilize the given information to determine the dominant species in the solution and subsequently calculate their pH values. Each response must include the major species present in the solution as well as the pH, which you should enter in the spaces provided above.
