**Ammonia and Ammonium Chloride Solution – Hydroxide Concentration Calculation** This educational resource will guide you through determining the hydroxide ion concentration \([OH^-]\) of an ammonia and ammonium chloride solution. ### Problem Statement An ammonia (\(NH_3\)) and ammonium chloride (\(NH_4Cl\)) solution has the concentrations listed below the reaction. What is the hydroxide concentration of the solution? ### Reaction \[ \text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons \text{NH}_4^+ + \text{OH}^- \] ### Given Concentrations - Ammonia \( (\text{NH}_3) \) concentration: 0.75 M - Ammonium ion \( (\text{NH}_4^+) \) concentration: 0.25 M ### Reaction Constant - Base dissociation constant (\(K_b\)) for ammonia (\( \text{NH}_3 \)): \(1.8 \times 10^{-5}\) ### Calculation Goal Determine the hydroxide ion concentration \([OH^-]\) of the solution. The formula for the dissociation constant \(K_b\) is: \[ K_b = \frac{[\text{NH}_4^+][\text{OH}^-]}{[\text{NH}_3]} \] ### Solution Format \[ [OH^-] = \boxed{?} \times 10^{\boxed{?}} \text{ M} \] Please enter your coefficients in the respective fields provided for coefficient (green) and exponent (yellow). ### Interactive Component To facilitate understanding and ensure the calculation accuracy, an interactive form is presented where users can input coefficients: - Coefficient (green field): input the numeric coefficient. - Exponent (yellow field): input the exponent value. Click "Enter" to check your answer. By following these steps and using the provided information, you can effectively calculate the hydroxide ion concentration for the given solution.
