FeSO\u2084 is composed of iron (Fe\u00b2\u207a) and the sulfate ion (SO\u2084\u00b2\u207b). The overall compound is neutral, meaning the positive and negative charges must balance out.<\/p>\n\n\n\n<p>In this compound:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Iron (Fe) has an oxidation state of <strong>+2<\/strong>, because it forms the ferrous ion Fe\u00b2\u207a.<\/li>\n\n\n\n<li>The sulfate ion (SO\u2084\u00b2\u207b) has a total charge of <strong>-2<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Within the sulfate ion (SO\u2084\u00b2\u207b), oxygen always has an oxidation state of <strong>-2<\/strong>. There are four oxygen atoms, contributing a total of <strong>4 \u00d7 -2 = -8<\/strong>.<\/p>\n\n\n\n<p>Let the oxidation state of sulfur be <strong>x<\/strong>. Since the total charge of the sulfate ion is -2, the sum of the oxidation states of sulfur and oxygen must equal -2:<\/p>\n\n\n\n<p><strong>x + (-8) = -2<\/strong><\/p>\n\n\n\n<p>Solving for x:<\/p>\n\n\n\n<p><strong>x = -2 + 8 = +6<\/strong><\/p>\n\n\n\n<p>Therefore, sulfur has an oxidation state of <strong>+6<\/strong> in FeSO\u2084.<\/p>\n\n\n\n<p>This value makes sense based on known chemistry. Sulfur is a multivalent nonmetal and can exhibit oxidation states ranging from -2 to +6. In sulfate compounds, sulfur is consistently found in the +6 oxidation state because it forms stable tetrahedral SO\u2084\u00b2\u207b ions. These ions are commonly found in salts like FeSO\u2084, CuSO\u2084, and ZnSO\u2084.<\/p>\n\n\n\n<p>Knowing oxidation states is important in redox chemistry, chemical reactions, and determining electron transfer. It also helps classify compounds and understand their reactivity. In this case, FeSO\u2084 is often used in chemistry labs and medicine, and understanding its composition is essential to predict how it behaves chemically.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the oxidation state of S in FeSO4 The correct answer and explanation is: The correct oxidation state of sulfur (S) in FeSO\u2084 is +6.
