Identify the pure substances and mixture from the following list : (a) solid common salt (b) milk (c) air (d) oxygen (e) fruit juice (f) brass (g) copper sulphate crystals (h) distilled water (i) sugar solution (j) honey (k) Ice cream (l) Iron sulphide<\/p>\n\n\n\n

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

Here\u2019s the classification of each substance from the list:<\/p>\n\n\n\n

Pure Substances:<\/h3>\n\n\n\n
    \n
  1. Solid Common Salt (a)<\/strong> \u2013 This is a pure substance<\/strong>. It is made up entirely of sodium chloride (NaCl) and does not contain any other components. The composition is uniform throughout.<\/li>\n\n\n\n
  2. Oxygen (d)<\/strong> \u2013 Oxygen is a pure substance<\/strong>. It consists only of O\u2082 molecules and has a consistent composition.<\/li>\n\n\n\n
  3. Copper Sulphate Crystals (g)<\/strong> \u2013 Copper sulfate (CuSO\u2084) in its solid form is a pure substance<\/strong> because it is made up of a specific chemical compound in a uniform structure.<\/li>\n\n\n\n
  4. Distilled Water (h)<\/strong> \u2013 Distilled water is a pure substance<\/strong>. It contains only H\u2082O molecules and has been purified of any impurities or solutes.<\/li>\n<\/ol>\n\n\n\n

    Mixtures:<\/h3>\n\n\n\n
      \n
    1. Milk (b)<\/strong> \u2013 Milk is a mixture<\/strong>. It contains water, fats, proteins, lactose, and minerals, all combined together but not chemically bonded. It is a heterogeneous mixture.<\/li>\n\n\n\n
    2. Air (c)<\/strong> \u2013 Air is a mixture<\/strong>. It is made up of several gases, primarily nitrogen, oxygen, carbon dioxide, and other trace gases, which are physically mixed but not chemically bonded.<\/li>\n\n\n\n
    3. Fruit Juice (e)<\/strong> \u2013 Fruit juice is a mixture<\/strong>. It consists of water, sugars, vitamins, and other components from fruit, combined together but not chemically bound.<\/li>\n\n\n\n
    4. Brass (f)<\/strong> \u2013 Brass is an alloy mixture<\/strong>, primarily made of copper and zinc. The two metals are physically mixed together but are not chemically bonded.<\/li>\n\n\n\n
    5. Sugar Solution (i)<\/strong> \u2013 A sugar solution is a mixture<\/strong>. It consists of sugar (sucrose) dissolved in water. The sugar can be physically separated from the water, indicating it’s a mixture.<\/li>\n\n\n\n
    6. Honey (j)<\/strong> \u2013 Honey is a mixture<\/strong>. It is made up of water, sugars, enzymes, and other compounds. These components are mixed but not chemically bonded.<\/li>\n\n\n\n
    7. Ice Cream (k)<\/strong> \u2013 Ice cream is a mixture<\/strong>. It is a combination of water, fats, sugars, proteins, and air that are physically mixed together.<\/li>\n\n\n\n
    8. Iron Sulphide (l)<\/strong> \u2013 Iron sulfide (FeS) is a pure substance<\/strong> when it is in its solid form. However, if it is mixed with other components, it could become a mixture. Pure iron sulfide is a compound, a specific chemical combination of iron and sulfur.<\/li>\n<\/ol>\n\n\n\n

      Conclusion:<\/h3>\n\n\n\n
        \n
      • Pure substances<\/strong>: Solid common salt, oxygen, copper sulfate crystals, distilled water.<\/li>\n\n\n\n
      • Mixtures<\/strong>: Milk, air, fruit juice, brass, sugar solution, honey, ice cream.<\/li>\n<\/ul>\n\n\n\n

        Pure substances have a fixed composition, while mixtures contain two or more substances that are physically combined.<\/p>\n\n\n\n
