Alcohols are so weakly acidic that, for normal lab purposes, their acidity can be virtually ignored. phenol are soluble in naoh because the reaction between phenol and naoh is exothermic and equilibrium lies to right that makes phenol stable. Phenol is acidic. The sodium salt of phenol, sodium phenoxide, is far more water-soluble.

What is real metals used as Bi-Metal in Thermostat ? The passage said that phenol would dissolve in NaOH but that benzyl alcohol wouldn't. Use the BACK button (or HISTORY file or GO menu) on your browser to return to this page. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Hey mate.... the answer is. Find out more about how we use your information in our Privacy Policy and Cookie Policy. Do radioactive elements cause water to heat up? Though phenol can be identified from alcohols from the reaction with aqueous NaOH, you cannot idenstify phenol from carboxylic acids because, carboxylic acids react with aqueous NaOH. Phenol reacts with sodium hydroxide solution to give a colourless solution containing sodium phenoxide. You will need to use the BACK BUTTON on your browser to come back here afterwards. With sodium hydroxide solution. Sciences, Culinary Arts and Personal Performance & security by Cloudflare, Please complete the security check to access.

Still have questions? The reason why phenol is more soluble in NaOH than in water is because phenol is slightly acidic. The reason why phenol is more soluble in NaOH than in water is because phenol is slightly acidic. NaOH itself is a solid. HCI. Note also that inspite of the polar -OH group, this molecule is still not soluble because the -OH group is small in comparison to the rest of the molecule. . This makes the sodium phenoxide extra stable. PLEASE Dont forget to talk about anthracene! I had a practice MCAT question that was discussing the solubility of phenol and benzyl alcohol in NaOH and NaHCO3. How do you think about the answers? Phenol reacts with sodium hydroxide solution to give a colourless solution containing sodium phenoxide. You can recognise phenol because: It reacts with sodium hydroxide solution to give a colourless solution (and therefore must be acidic). The Ka for phenol in water is 1e-10. Like sodium chloride (NaCl), NaOPh is soluble. Find more answers. Hence it is soluble in moderately strong to strong bases like NaOH, Na2CO3 etc.. Let's be more exact, you are talking about NaOH in aqueous solution. Question: Phenol is soluble in NaOH (aq) and not NaHCO3 (aq) while benzoic acid is soluble in both solutions. To the menu of other organic compounds . Litmus paper is blue at pH 8 and red at pH 5. All other trademarks and copyrights are the property of their respective owners. It doesn't produce carbon dioxide with sodium carbonate or hydrogencarbonate solutions (and so must be only very weakly acidic). - Definition, Process & Apparatus, Vibrational Spectroscopy: Definition & Types, Regioselectivity, Stereoselectivity & Chemoselectivity: Definitions & Examples, Valence Bond Theory of Coordination Compounds, What Are Chromophores & Auxochromes? - Definitions & Types, What Is an Alkaloid? why is phenol more soluble in sodium hydroxide than water?
