What is the correct IUPAC name for Cr2(SO4)3<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Correct IUPAC Name:<\/h3>\n\n\n\n

The correct IUPAC name for Cr\u2082(SO\u2084)\u2083<\/strong> is Chromium(III) sulfate<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The compound Cr\u2082(SO\u2084)\u2083<\/strong> consists of chromium (Cr)<\/strong> and the sulfate ion (SO\u2084\u00b2\u207b)<\/strong>. To name it correctly, we follow the IUPAC rules for naming ionic compounds.<\/p>\n\n\n\n

Step 1: Identify the Cation and Its Oxidation State<\/strong><\/h4>\n\n\n\n
    \n
  • Chromium (Cr)<\/strong> is a transition metal, which means it can have multiple oxidation states.<\/li>\n\n\n\n
  • The sulfate ion (SO\u2084\u00b2\u207b) has a charge of -2<\/strong>.<\/li>\n\n\n\n
  • Since there are three sulfate ions in the formula, the total negative charge is 3 \u00d7 (-2) = -6<\/strong>.<\/li>\n\n\n\n
  • There are two chromium (Cr) atoms in the formula, so let\u2019s assign an oxidation number x<\/strong> to each chromium atom: [
    2(x) + 3(-2) = 0
    ]
    [
    2x – 6 = 0
    ]
    [
    2x = 6
    ]
    [
    x = +3
    ]<\/li>\n<\/ul>\n\n\n\n

    Thus, the oxidation state of chromium in this compound is +3<\/strong>.<\/p>\n\n\n\n

    Step 2: Naming the Cation<\/strong><\/h4>\n\n\n\n

    Since chromium has a +3 charge, we indicate this using Roman numerals in parentheses: Chromium(III)<\/strong>.<\/p>\n\n\n\n

    Step 3: Naming the Anion<\/strong><\/h4>\n\n\n\n

    The anion present is sulfate (SO\u2084\u00b2\u207b)<\/strong>, which retains its name in the compound.<\/p>\n\n\n\n

    Final Name:<\/strong><\/h4>\n\n\n\n

    Putting it together, the correct IUPAC name is Chromium(III) sulfate<\/strong>.<\/p>\n\n\n\n

    This naming follows standard IUPAC conventions for transition metal compounds, where the oxidation state of the metal is explicitly mentioned.<\/p>\n\n\n\n

    Now, I will generate an image representing Chromium(III) sulfate’s<\/strong> molecular structure.<\/p>\n\n\n\n
