Capitolo 4, Problema 10b
An aqueous solution contains 1.2 mM of total ions. (b) If the solution is FeCl3(aq), what is the concentration of chloride ion?
Guida verificata passo dopo passo1
Identify the dissociation equation for FeCl_3 in water: FeCl_3(aq) \(\rightarrow\) Fe^{3+}(aq) + 3Cl^{-}(aq).
Recognize that for every 1 mole of FeCl_3 that dissociates, 3 moles of Cl^- ions are produced.
Given that the total concentration of ions is 1.2 mM, determine the concentration of FeCl_3 by considering the stoichiometry of the dissociation.
Calculate the concentration of Cl^- ions by multiplying the concentration of FeCl_3 by 3, as each FeCl_3 produces 3 Cl^- ions.
Express the concentration of Cl^- ions in mM, ensuring the units are consistent with the given total ion concentration.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Dissociation of Ionic Compounds
Ionic compounds, such as FeCl3, dissociate into their constituent ions when dissolved in water. For FeCl3, it separates into one Fe³⁺ ion and three Cl⁻ ions. Understanding this dissociation is crucial for calculating the concentration of individual ions in a solution.

Ionic Compounds Naming
Molarity and Concentration
Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution. In this case, the total ion concentration is given in millimoles per liter (mM), which can be converted to moles per liter. This concept is essential for determining the concentration of specific ions in the solution.

Stoichiometry in Solutions
Stoichiometry involves the quantitative relationships between reactants and products in a chemical reaction. In the context of this question, it helps to determine the ratio of ions produced from the dissociation of FeCl3, allowing us to calculate the concentration of chloride ions based on the total ion concentration.

Domanda del libro di testo
You are titrating an acidic solution with a basic one, and just realized you forgot to add the indicator that tells you when the equivalence point is reached. In this titration, the indicator turns blue at the equivalence point from an initially colorless solution. You quickly grab a bottle of indicator and add some to your titration beaker, and the whole solution turns dark blue. What do you do now?
