Hypochlorite<br>B. Acetate<br>D. Bicarbonate<br>E. Nitrite<br>F. Hydroxide<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Polyatomic ions are charged groups of covalently bonded atoms that behave as a unit. These ions can either carry a positive charge (cations) or a negative charge (anions). An <strong>anion<\/strong> is a negatively charged ion, which means it has gained one or more electrons.<\/p>\n\n\n\n<p>Let us examine each of the listed ions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hypochlorite (ClO\u207b):<\/strong> This ion consists of chlorine and oxygen, carrying a negative charge. It is an anion and commonly found in bleaching agents and disinfectants.<\/li>\n\n\n\n<li><strong>Acetate (C\u2082H\u2083O\u2082\u207b or CH\u2083COO\u207b):<\/strong> This negatively charged ion is derived from acetic acid. It is an anion and commonly found in vinegar and biological metabolic processes.<\/li>\n\n\n\n<li><strong>Ammonium (NH\u2084\u207a):<\/strong> This is a <strong>cation<\/strong>, not an anion. It carries a positive charge and is formed when ammonia accepts a proton. It is commonly found in fertilizers and cleaning products.<\/li>\n\n\n\n<li><strong>Bicarbonate (HCO\u2083\u207b):<\/strong> This is a negatively charged ion formed when carbonic acid loses one hydrogen ion. It is an important buffer in blood and other biological fluids, making it an anion.<\/li>\n\n\n\n<li><strong>Nitrite (NO\u2082\u207b):<\/strong> This negatively charged ion contains nitrogen and oxygen. It is an anion and often occurs in food preservatives and the nitrogen cycle.<\/li>\n\n\n\n<li><strong>Hydroxide (OH\u207b):<\/strong> This ion carries a negative charge and consists of oxygen and hydrogen. It is a strong base and is classified as an anion.<\/li>\n<\/ul>\n\n\n\n<p>In summary, all the listed ions are anions <strong>except ammonium<\/strong>, which is a cation. Understanding the charge of polyatomic ions is important in predicting chemical behavior, bonding, and how compounds will form in solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which polyatomic ions are anions?A HypochloriteB AcetateC AmmoniumD BicarbonateE NitriteF Hydroxide The correct answer and explanation is: Correct Answers:A.
