To write its correct chemical formula, it is important to understand the charges of each ion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potassium (K) is an <strong>alkali metal<\/strong> from Group 1 of the periodic table. It loses one electron to form a <strong>K\u207a<\/strong> ion, which carries a <strong>+1 charge<\/strong>.<\/li>\n\n\n\n<li>Sulfite is a <strong>polyatomic ion<\/strong> with the formula <strong>SO\u2083\u00b2\u207b<\/strong>. It carries a <strong>-2 charge<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>In an ionic compound, the total positive charge must balance the total negative charge. The sulfite ion has a 2\u2013 charge, and each potassium ion has a 1+ charge. To balance the charges, two potassium ions are needed for every one sulfite ion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>2 K\u207a ions \u2192 total charge = +2<\/li>\n\n\n\n<li>1 SO\u2083\u00b2\u207b ion \u2192 total charge = \u20132<\/li>\n<\/ul>\n\n\n\n<p>These charges cancel out, creating a <strong>neutral<\/strong> compound. So the correct chemical formula becomes:<\/p>\n\n\n\n<p><strong>K\u2082SO\u2083<\/strong><\/p>\n\n\n\n<p>This formula shows that <strong>two potassium ions<\/strong> combine with <strong>one sulfite ion<\/strong> to form potassium sulfite.<\/p>\n\n\n\n<p>Potassium sulfite is used in some industrial and food applications, particularly as a <strong>preservative<\/strong> and in <strong>photographic<\/strong> and <strong>textile processing<\/strong>. The compound is <strong>highly soluble<\/strong> in water and acts as a <strong>reducing agent<\/strong>. It is different from potassium sulfate (K\u2082SO\u2084), which contains the <strong>sulfate ion (SO\u2084\u00b2\u207b)<\/strong> rather than sulfite (SO\u2083\u00b2\u207b).<\/p>\n\n\n\n<p>In summary, understanding the charges of the ions and ensuring the total positive and negative charges are equal allows for writing the correct formula: <strong>K\u2082SO\u2083<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the correct formula for potassium sulfite The correct answer and explanation is: Correct Answer: The formula for potassium sulfite is K\u2082SO\u2083.
