To solve the problem of how many grams of \( NH_4NO_3 \) should be dissolved per liter of solution to achieve a pH of 5.13, we can follow these steps: ### Step 1: Understand the Dissociation of \( NH_4NO_3 \) When \( NH_4NO_3 \) dissolves in water, it dissociates into \( NH_4^+ \) and \( NO_3^- \). The \( NH_4^+ \) ion is the conjugate acid of the weak base \( NH_3 \). ### Step 2: Determine the Relationship Between pH and \( NH_4^+ \) Since \( NH_4^+ \) is a weak acid, we can use the formula for the pH of a weak acid: \[ ...
