In hydrogen sulfide, sulfur typically has an oxidation state of -2, as it is more electronegative than hydrogen.<\/li>\n<\/ul>\n\n\n\n<p>e. <strong>CO\u2083\u00b2\u207b (Carbonate ion)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>C (Carbon)<\/strong> has an oxidation state of <strong>+4<\/strong>.

Oxygen in most compounds, except peroxides, typically has an oxidation state of -2.<\/li>\n<\/ul>\n\n\n\n<p>f. <strong>CrO\u2084\u00b2\u207b (Chromate ion)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cr (Chromium)<\/strong> has an oxidation state of <strong>+6<\/strong>.
