Transition metals are well known for forming colored compounds due to the unique way their electrons behave. In particular, the <strong>d-electrons<\/strong> in transition metal ions can absorb certain wavelengths of visible light. When these d-electrons are excited to higher energy levels (a process called <strong>d\u2013d transitions<\/strong>), they absorb parts of the visible light spectrum. The remaining unabsorbed light is what we see as the compound\u2019s color. <strong>Nickel chloride<\/strong> typically appears <strong>bright green<\/strong> in its hydrated form (e.g., NiCl\u2082\u00b76H\u2082O).<\/p>\n\n\n\n<p>On the other hand, the other three compounds \u2014 <strong>potassium chloride<\/strong>, <strong>lithium chloride<\/strong>, and <strong>hydrogen chloride<\/strong> \u2014 do <strong>not contain transition metals<\/strong>. Potassium (K\u207a), lithium (Li\u207a), and hydrogen (H\u207a) are <strong>alkali metals or non-metals<\/strong> whose ions do not have partially filled d-orbitals. As a result, they do <strong>not<\/strong> absorb visible light in the same way and are typically <strong>colorless<\/strong> or <strong>white<\/strong> in solid form and clear in solution.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Potassium chloride<\/strong> is usually a <strong>white crystalline solid<\/strong>.<\/li>\n\n\n\n<li><strong>Lithium chloride<\/strong> is also a <strong>white solid<\/strong>.<\/li>\n\n\n\n<li><strong>Hydrogen chloride<\/strong>, in its aqueous form (hydrochloric acid), is a <strong>colorless solution<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, <strong>nickel chloride<\/strong> stands out for its <strong>vivid green color<\/strong> due to its transition metal character, making it the correct answer.<\/p>\n\n\n\n<p><strong>Summary<\/strong>: Only <strong>nickel chloride<\/strong> contains a transition metal capable of producing visible color through d-electron transitions, making it the only compound among the four that shows a vivid color.<\/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-banner6-79.jpeg\" alt=\"\" class=\"wp-image-228201\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which solution below most likely shows a vivid color?
