What is the formula for copper I sulfide?<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer:<\/strong> The formula for copper(I) sulfide is Cu\u2082S<\/strong>.<\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n Copper(I) sulfide is a chemical compound formed from copper and sulfur. To determine its formula, one must consider the charges of the ions that make up the compound. Copper(I) refers to copper in the +1 oxidation state. This means each copper ion has a charge of +1, and it is represented as Cu\u207a. Sulfide is the name given to the anion of sulfur, which always carries a -2 charge, written as S\u00b2\u207b.<\/p>\n\n\n\n In order to form a neutral compound, the total positive and negative charges must balance each other. Since each Cu\u207a ion contributes a +1 charge, and the S\u00b2\u207b ion contributes a -2 charge, two copper(I) ions are required to balance one sulfide ion:<\/p>\n\n\n\n (+1) + (+1) = +2 from copper The total charge is +2 and -2, which cancel each other out, resulting in a neutral compound. Therefore, the formula is written as Cu\u2082S, indicating two copper(I) ions for every one sulfide ion.<\/p>\n\n\n\n It is important not to confuse copper(I) with copper(II). Copper can exist in multiple oxidation states, most commonly +1 and +2. Copper(II) sulfide would have the formula CuS because Cu\u00b2\u207a balances with S\u00b2\u207b in a 1:1 ratio. In contrast, copper(I) requires a 2:1 ratio to achieve neutrality.<\/p>\n\n\n\n The naming of copper(I) sulfide follows the Stock system, which uses Roman numerals to indicate the oxidation state of a metal that can form more than one ion. Since copper can form both Cu\u207a and Cu\u00b2\u207a, the numeral I is used to specify that the copper in Cu\u2082S is in the +1 oxidation state.<\/p>\n","protected":false},"excerpt":{"rendered":" What is the formula for copper I sulfide?
