To understand this name and how the formula is derived, we must first look at the components of the compound:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Calcium (Ca):<\/strong><br>Calcium is a metal from <strong>Group 2 (alkaline earth metals)<\/strong> of the periodic table. Elements in this group typically form <strong>+2 cations (Ca\u00b2\u207a)<\/strong> when they lose two electrons.<\/li>\n\n\n\n<li><strong>Sulfite (SO\u2083\u00b2\u207b):<\/strong><br>Sulfite is a <strong>polyatomic ion<\/strong> consisting of one sulfur atom bonded to three oxygen atoms. It carries a <strong>\u22122 charge<\/strong> overall. It is important not to confuse it with <strong>sulfate (SO\u2084\u00b2\u207b)<\/strong>, which has one more oxygen atom than sulfite.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">To form a neutral ionic compound, the charges of the cation and anion must <strong>balance<\/strong>. In this case:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ca\u00b2\u207a (calcium ion) has a charge of +2<\/li>\n\n\n\n<li>SO\u2083\u00b2\u207b (sulfite ion) has a charge of \u22122<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Since both ions have charges of equal magnitude but opposite signs, <strong>only one of each ion is needed<\/strong> to balance the charges, leading to the formula:<br><strong>CaSO\u2083<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This compound is named by <strong>naming the metal first<\/strong> (calcium) followed by the name of the polyatomic ion (sulfite), without any prefixes or suffixes. Hence, the correct name is <strong>calcium sulfite<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Uses and Properties:<\/strong><br>Calcium sulfite is often used as a <strong>preservative<\/strong> or <strong>antioxidant<\/strong>, especially in the food and beverage industries. It can also appear as a byproduct in industrial processes, particularly in <strong>flue-gas desulfurization<\/strong>, where it helps reduce sulfur dioxide emissions. It is a white or off-white powder that is <strong>sparingly soluble in water<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the nomenclature of compounds like calcium sulfite helps in studying chemical reactions, predicting products, and interpreting chemical behavior.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner9-82.jpeg\" alt=\"\" class=\"wp-image-227421\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the name of the compound with the formula CaSO3 The Correct Answer and Explanation is: The name of the compound with the formula CaSO\u2083 is calcium sulfite.
