It is a yellow solid that is soluble in water. The preparation of aniline yellow involves the reaction of aniline with sulfuric acid.<\/p>\n<p>The experiment begins by weighing out 0.5 grams of aniline. The aniline is then placed in a conical flask, and 10 milliliters of sulfuric acid are added. The flask is then placed on a hotplate, and the mixture is heated until it begins to boil. The mixture is then boiled for 15 minutes. After boiling for 15 minutes, the mixture is allowed to cool. The aniline yellow is then isolated by filtration.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Apparatus_Required\"><\/span>Apparatus Required<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To perform a titration, you will need a volumetric flask, a burette, a pipette, and a stirring rod.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Theory\"><\/span>Theory<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This experiment&#8217;s objective was to synthesize aniline yellow from aniline and benzoic acid. The first step was to dissolve aniline and benzoic acid in ethanol. Next, NaOH was added to the solution to form a benzoate anion and protons. The benzoate anion then reacted with the aniline to form aniline hydrochloride and benzoic acid. The aniline hydrochloride then reacted with the ethanol to form aniline yellow.<\/p>\n<p>The first step of the experiment was to dissolve aniline and benzoic acid in ethanol. Aniline is a colorless, oily liquid, and benzoic acid is a white crystalline solid. When they were dissolved in ethanol, they formed a yellow solution.<\/p>\n<p>The next step was to add NaOH to the solution. NaOH is a strong base, and it reacts with the benzoate anion to form benzoate ions and protons. The benzoate ion then reacted with the aniline to form aniline hydrochloride and benzoic acid.<\/p>\n<p>The aniline hydrochloride then reacted with the ethanol to form aniline yellow. Aniline yellow is a yellow crystalline solid. It is insoluble in water but soluble in ethanol.<\/p>\n<p>The results of this experiment showed that aniline and benzoic acid could be used to form aniline yellow. Aniline yellow is a yellow crystalline solid that is insoluble in water but soluble in ethanol.<\/p>\n<p class=\"entry-title\"><a href=\"https:\/\/infinitylearn.com\/surge\/study-materials\/ncert-solutions\/class-12\/chemistry\/\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #0000ff;\">NCERT Solutions for Class 12 Chemistry<\/span><\/a><\/p>\n<p><a href=\"https:\/\/infinitylearn.com\/surge\/study-materials\/ncert-solutions\/class-11\/chemistry\/\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #0000ff;\">NCERT Solutions for Class 11 Chemistry<\/span><\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Chemical_Reaction_Involved\"><\/span>The Chemical Reaction Involved<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>in the Formation of a Salt<\/p>\n<p>When an acid and a base react, salt and water are produced.
