### QuestionWhat is the pH of 0.03 M NH₄Br (aq)?### Options- ○ 3.13 - ○ 9.25 - ○ 10.87 - ○ 1.52 - ○ 5.38 ### ExplanationThis question asks for the pH of an aqueous solution of ammonium bromide (NH₄Br) at a concentration of 0.03 M. To solve this, you need to consider the dissociation of NH₄Br in water and the effect of NH₄⁺ (ammonium ion) on the pH, since it can act as a weak acid. This requires knowledge of the acidity constant (Ka) for NH₄⁺ and the use of the formula:\[ \text{pH} = -\log [\text{H}^+] \]By calculating the concentration of H⁺ ions produced and determining the pH, you can select the correct answer.
