Potassium permanganate.<\/p>\n<p>Potassium permanganate is a strong oxidizing agent that can be used to detect the presence of nitrates in sewage. When potassium permanganate is added to a solution of nitrates, it will react with the nitrates to form a brown precipitate. The amount of brown precipitate that forms will be proportional to the concentration of nitrates in the solution.<\/p>\n<p>Sulphuric acid and napthamine are not effective in detecting the presence of nitrates. Phenol-di -sulphuric acid and potassium hydroxide are also not effective in detecting the presence of nitrates.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li>Option A: Potassium permanganate is a strong oxidizing agent that can be used to detect the presence of nitrates in sewage. When potassium permanganate is added to a solution of nitrates, it will react with the nitrates to form a brown precipitate. The amount of brown precipitate that forms will be proportional to the concentration of nitrates in the solution.<\/li>\n<li>Option B: Sulphuric acid and napthamine are not effective in detecting the presence of nitrates. Sulphuric acid is a strong acid that can react with many different substances, including nitrates. However, the reaction between sulphuric acid and nitrates does not produce a visible change that can be used to detect the presence of nitrates. Napthamine is a colorless organic compound that does not react with nitrates. Therefore, sulphuric acid and napthamine cannot be used to detect the presence of nitrates.<\/li>\n<li>Option C: Phenol-di -sulphuric acid and potassium hydroxide are also not effective in detecting the presence of nitrates. Phenol-di -sulphuric acid is a strong acid that can react with many different substances, including nitrates. However, the reaction between phenol-di -sulphuric acid and nitrates does not produce a visible change that can be used to detect the presence of nitrates. Potassium hydroxide is a strong base that can react with many different substances, including nitrates. However, the reaction between potassium hydroxide and nitrates does not produce a visible change that can be used to detect the presence of nitrates. Therefore, phenol-di -sulphuric acid and potassium hydroxide cannot be used to detect the presence of nitrates.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Potassium permanganate&#8221; option2=&#8221;Sulphuric acid and napthamine&#8221; option3=&#8221;Phenol-di -sulphuric acid and potassium hydroxide&#8221; option4=&#8221;None of these&#8221; correct=&#8221;option1&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[650],"tags":[],"class_list":["post-7807","post","type-post","status-publish","format-standard","hentry","category-waste-water-engineering","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>For detecting the nitrates in sewage, the colour may be developed by adding A.
