CuN2O4 Cu(NO3)2 CuN2O6<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>The correct formula for copper (II) nitrite is <strong>Cu(NO\u2082)\u2082<\/strong>.<\/p>\n\n\n\n<p>To determine this formula, we need to consider the oxidation states of the elements involved. Copper (II) refers to copper with a +2 oxidation state, denoted as Cu\u00b2\u207a. Nitrite is the polyatomic ion NO\u2082\u207b, which carries a charge of -1. To form a neutral compound, the charges must balance. This means that one Cu\u00b2\u207a ion requires two NO\u2082\u207b ions to counterbalance its charge, resulting in Cu(NO\u2082)\u2082.<\/p>\n\n\n\n<p>A common mistake is confusing nitrite (NO\u2082\u207b) with nitrate (NO\u2083\u207b). Copper (II) nitrate, which contains the NO\u2083\u207b ion, would have the formula Cu(NO\u2083)\u2082 instead. However, the question asks for the nitrite compound.<\/p>\n\n\n\n<p>Chemical compounds follow strict rules of nomenclature and formula writing based on charge neutrality and empirical composition. For copper (II) nitrite, the subscript \u201c2\u201d in NO\u2082 indicates that two nitrite ions are required to balance the charge of one copper (II) ion.<\/p>\n\n\n\n<p>Looking at the provided options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CuN\u2082O\u2084 does not correspond to any known copper nitrite formula.<\/li>\n\n\n\n<li>Cu(NO\u2083)\u2082 is copper (II) nitrate, which contains nitrate rather than nitrite.<\/li>\n\n\n\n<li>CuN\u2082O\u2086 does not follow conventional notation for copper nitrite.<\/li>\n<\/ul>\n\n\n\n<p>Thus, Cu(NO\u2082)\u2082 is the correct answer. This compound consists of copper ions and nitrite ions, typically appearing as a crystalline solid with limited solubility in water. Its applications include specialized chemical processes and laboratory reactions. Understanding the difference between nitrite and nitrate is crucial in inorganic chemistry, as both ions exhibit distinct reactivity and bonding characteristics.<\/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-banner8-817.jpeg\" alt=\"\" class=\"wp-image-237339\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the formula for copper (II) nitrite?
