Write the ions present in solution of K2CO3. Express your answers as chemical formulas separated by a comma. Identify all of the phases in your answers.<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

When potassium carbonate (K\u2082CO\u2083) dissolves in water, it dissociates into its constituent ions:<\/p>\n\n\n\n

K\u2082CO\u2083 (s) \u2192 2 K\u207a (aq) + CO\u2083\u00b2\u207b (aq)<\/strong><\/p>\n\n\n\n

This means that for every formula unit of K\u2082CO\u2083 that dissolves, two potassium ions (K\u207a) and one carbonate ion (CO\u2083\u00b2\u207b) are produced in the aqueous phase.<\/p>\n\n\n\n

  1. Dissociation of Ionic Compounds:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Ionic compounds like K\u2082CO\u2083 consist of positively charged cations and negatively charged anions held together by electrostatic forces.<\/li>\n\n\n\n
    • When such compounds dissolve in water, the polar water molecules surround and separate these ions, allowing them to move freely in solution.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Stoichiometry of K\u2082CO\u2083:<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • The chemical formula K\u2082CO\u2083 indicates that each formula unit contains two potassium ions (K\u207a) and one carbonate ion (CO\u2083\u00b2\u207b).<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Phases of Ions:<\/strong><\/li>\n<\/ol>\n\n\n\n
              \n
            • In the dissociation equation, “(s)” denotes a solid, indicating that K\u2082CO\u2083 is in solid form before dissolution.<\/li>\n\n\n\n
            • “(aq)” denotes an aqueous solution, indicating that the ions are dissolved in water.<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Electrical Conductivity:<\/strong><\/li>\n<\/ol>\n\n\n\n
                  \n
                • The presence of free-moving ions in the aqueous solution allows it to conduct electricity, a property characteristic of electrolytes.<\/li>\n<\/ul>\n\n\n\n
                    \n
                  1. Reversibility:<\/strong><\/li>\n<\/ol>\n\n\n\n
                      \n
                    • The dissociation of K\u2082CO\u2083 in water is a reversible process. Under certain conditions, such as evaporation of water, the ions can recombine to form solid K\u2082CO\u2083 again.<\/li>\n<\/ul>\n\n\n\n

                      Understanding the dissociation of K\u2082CO\u2083 is fundamental in various chemical processes, including acid-base reactions, precipitation reactions, and in the study of colligative properties of solutions.<\/p>\n\n\n\n
