Metallic copper is used for the manufacture of water pipes and electrical wires. Copper sulphate is blue. Copper is less reactive than iron; thus, iron can replace copper easily. It is a chemical change. When Copper sulphate is heated strongly, it changes into white anhydrous copper sulphate and when water is added again to it then it is again changed to blue colour copper sulphate. <\/span><br><math xmlns=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mi mathvariant=\"italic\">Fe<\/mi><mo>+<\/mo><mi mathvariant=\"italic\">CuS<\/mi><msub><mrow><mi>O<\/mi><\/mrow><mrow><mn>4<\/mn><\/mrow><\/msub><mo>\u2192<\/mo><mi mathvariant=\"italic\">FeS<\/mi><msub><mrow><mi>O<\/mi><\/mrow><mrow><mn>4<\/mn><\/mrow><\/msub><mo>+<\/mo><mi mathvariant=\"italic\">Cu<\/mi><\/math><br><span>&nbsp;<\/span>","subject":"Chemistry"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which of the following types of changes occurs when iron reacts with copper sulphate?
