To understand this compound, it is essential to analyze the individual parts.<\/p>\n\n\n\n<p>Iron (Fe) is a transition metal and can exhibit multiple oxidation states. In this compound, the iron ion is in the +3 oxidation state, indicated by the Roman numeral III in the name. This makes it an <strong>iron(III)<\/strong> ion, or <strong>Fe\u00b3\u207a<\/strong>.<\/p>\n\n\n\n<p>Bicarbonate is a <strong>polyatomic ion<\/strong> with the formula HCO\u2083\u207b. It carries a <strong>single negative charge (-1)<\/strong>. Since the iron ion carries a +3 charge, and each bicarbonate ion carries a -1 charge, three bicarbonate ions are needed to balance the charge of one Fe\u00b3\u207a ion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fe\u00b3\u207a + 3 \u00d7 HCO\u2083\u207b \u2192 Fe(HCO\u2083)\u2083<\/li>\n<\/ul>\n\n\n\n<p>This results in a neutral compound, meaning the positive and negative charges cancel each other out.<\/p>\n\n\n\n<p>The name of the compound follows IUPAC naming conventions. The metal comes first: <strong>Iron<\/strong>. Since iron can have more than one oxidation state, the specific state used in the compound must be indicated using Roman numerals: <strong>Iron(III)<\/strong>.<\/p>\n\n\n\n<p>The anion, HCO\u2083\u207b, is known as <strong>bicarbonate<\/strong> (or <strong>hydrogen carbonate<\/strong>). Since there are three of these ions in the compound, but they are all the same, no prefix is used, and the name simply becomes <strong>bicarbonate<\/strong>.<\/p>\n\n\n\n<p>Putting it together yields: <strong>Iron(III) bicarbonate<\/strong>.<\/p>\n\n\n\n<p>This compound may appear in contexts involving mineral reactions, environmental chemistry, or acid-base chemistry. The bicarbonate ion plays a significant role in pH buffering systems, especially in natural waters and biological systems.<\/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-banner5-563.jpeg\" alt=\"\" class=\"wp-image-235224\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the formula for the polyatomic ion Fe(HCO3)3 and it&#8217;s name The Correct Answer and Explanation is: Correct Answer: Formula: Fe(HCO\u2083)\u2083Name: Iron(III) bicarbonate Explanation: Fe(HCO\u2083)\u2083 is a compound that contains one iron (Fe) ion and three bicarbonate (HCO\u2083\u207b) ions.
