      Explanation<\/strong><\/h3>\n\n\n\n

      Potassium carbonate is an inorganic compound with the chemical formula K\u2082CO\u2083<\/strong>. It is composed of two potassium ions (K\u207a) and one carbonate ion (CO\u2083\u00b2\u207b). The carbonate ion is a polyatomic ion consisting of one carbon atom covalently bonded to three oxygen atoms. One of the oxygen atoms forms a double bond with the carbon, while the other two carry a negative charge each and are bonded via single bonds, forming a resonance-stabilized ion. This negative charge is balanced by the two positively charged potassium ions, resulting in a neutral compound overall.<\/p>\n\n\n\n

      The nomenclature of potassium carbonate follows the standard IUPAC naming system. “Potassium” refers to the cation K\u207a, while “carbonate” refers to the anion CO\u2083\u00b2\u207b. Since potassium is a Group 1 alkali metal and has a fixed +1 oxidation state, and carbonate is a common polyatomic anion with a \u22122 charge, the chemical formula must contain two<\/strong> potassium ions for every one<\/strong> carbonate ion to maintain charge neutrality, leading to the formula K\u2082CO\u2083<\/strong>.<\/p>\n\n\n\n

      To determine the molecular mass (also known as molar mass or formula weight) of potassium carbonate, we add the atomic masses of all the atoms in the formula:<\/p>\n\n\n\n

        \n
      • Potassium (K)<\/strong> has an atomic mass of 39 g\/mol<\/strong>. Since there are two potassium atoms, their combined mass is 78 g\/mol<\/strong>.<\/li>\n\n\n\n
      • Carbon (C)<\/strong> has an atomic mass of 12 g\/mol<\/strong>.<\/li>\n\n\n\n
      • Oxygen (O)<\/strong> has an atomic mass of 16 g\/mol<\/strong>, and since there are three oxygen atoms, the total oxygen mass is 48 g\/mol<\/strong>.<\/li>\n<\/ul>\n\n\n\n

        Adding these together gives the molecular mass:
        78 (K) + 12 (C) + 48 (O) = 138 g\/mol<\/strong><\/p>\n\n\n\n

        Potassium carbonate is a white salt, highly soluble in water, and commonly used in soaps, glass manufacturing, and as a buffering agent.<\/p>\n\n\n\n
