**Transcription for Educational Website:** --- **Question 7:** Which compound on the table below has the least molar solubility in water? - A) CdCO₃ - B) BaSO₄ - C) AgI - D) CuS **Table of Compounds and Solubility Products (Ksp):** | Name | Formula | Ksp | |----------------------|---------|---------------| | Cadmium carbonate | CdCO₃ | 5.2 x 10⁻¹² | | Barium sulfate | BaSO₄ | 1.07 x 10⁻¹⁰ | | Copper sulfide | CuS | 1.27 x 10⁻³⁶ | | Silver iodide | AgI | 8.3 x 10⁻¹⁷ | **Question 8:** The molar solubility of _______ does not increase by the addition of HCl. - A) NaNO₂ - B) NaF - C) Mg(OH)₂ - D) KBr --- **Explanation of the Table:** The table provides information about four different compounds, including their names, chemical formulas, and their respective solubility product constants (Ksp). The Ksp value is a measure of the solubility of a compound in water. A lower Ksp value indicates lower solubility, and vice versa. - **Cadmium carbonate (CdCO₃):** Ksp = 5.2 x 10⁻¹² - **Barium sulfate (BaSO₄):** Ksp = 1.07 x 10⁻¹⁰ - **Copper sulfide (CuS):** Ksp = 1.27 x 10⁻³⁶ - **Silver iodide (AgI):** Ksp = 8.3 x 10⁻¹⁷ Based on the Ksp values, Copper sulfide (CuS) has the lowest solubility, followed by Silver iodide (AgI), Cadmium carbonate (CdCO₃), and Barium sulfate (BaSO₄). **Graphical Representation:** This table represents the solubility product constants in scientific notation, providing a clear comparison between the solubilities of different compounds.
