### Chemical Compounds and Their Acid Dissociation Constants

- **HBr** 
- **NH₃**
- **NaCl**
- **NaC₂H₃O₂**
- **NaOH**
- **HCHO₂** (Formic Acid) 
  - **Ka = 1.8 × 10⁻⁴**
- **NH₄Cl**
- **HC₇H₅O₂** (Benzoic Acid) 
  - **Ka = 6.5 × 10⁻⁵**

**Explanation:**
- This list contains various chemical compounds, including acids, bases, and salts.
- The acid dissociation constant (Ka) values are provided for **HCHO₂** and **HC₇H₅O₂**, indicating the strength of these acids in aqueous solutions. The Ka value helps in understanding the degree of ionization of an acid in water.

This list can be used for educational purposes to identify and understand the properties of different chemical substances.
