The chemical formula of iodous acid is <strong>HIO\u2082<\/strong>, indicating it consists of <strong>one hydrogen (H)<\/strong>, <strong>one iodine (I)<\/strong>, and <strong>two oxygen (O)<\/strong> atoms.<\/p>\n\n\n\n<p>To determine the <strong>oxidation state (ionic charge) of iodine<\/strong>, we analyze the compound\u2019s structure and use typical oxidation numbers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hydrogen (H) almost always has an oxidation number of <strong>+1<\/strong>.<\/li>\n\n\n\n<li>Oxygen (O) almost always has an oxidation number of <strong>\u22122<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Let the oxidation number of iodine (I) be <strong>x<\/strong>. Then we set up the equation for the total charge of the molecule (which is neutral, so it equals 0):<\/p>\n\n\n\n<p>$$<br>(+1) + (x) + 2(\u22122) = 0<br>\\Rightarrow 1 + x \u2212 4 = 0<br>\\Rightarrow x = +3<br>$$<\/p>\n\n\n\n<p>Thus, the oxidation state\u2014or ionic charge\u2014of iodine in iodous acid is <strong>+3<\/strong>.<\/p>\n\n\n\n<p>Iodous acid is part of a group of iodine oxoacids, each with different oxidation states:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hypoiodous acid (HIO)<\/strong>: iodine is +1<\/li>\n\n\n\n<li><strong>Iodous acid (HIO\u2082)<\/strong>: iodine is +3<\/li>\n\n\n\n<li><strong>Iodic acid (HIO\u2083)<\/strong>: iodine is +5<\/li>\n\n\n\n<li><strong>Periodic acid (HIO\u2084 or H\u2085IO\u2086)<\/strong>: iodine is +7<\/li>\n<\/ul>\n\n\n\n<p>These differences arise because iodine, being a halogen in group 17, can exhibit multiple oxidation states, particularly when bonded to electronegative oxygen atoms.<\/p>\n\n\n\n<p>Iodous acid is relatively unstable and not commonly found in pure form. It exists primarily in aqueous solution and tends to disproportionate into other iodine compounds.
