WebMay 18, 2024 · The acidic portion of benzoic acid is the carboxyl group, and it reacts with a base to form a salt. For example, it reacts with sodium hydroxide (NaOH) to produce sodium benzoate, an ionic compound (C6H5COO- Na+). Both benzoic acid and sodium benzoate are used as food preservatives.

WebJun 6, 2016 · We can assume 0.1000 molar NaOH as the titrant and want to use about 30 ml of a 50 ml burette. That would mean weighing out about 3.0 millimoles of benzoic acid (0.37 grams) which would be dissolved in 25 ml of distilled water. Significant Figures All calculations done in chemistry involve errors. WebWrite your titration volumes for the standardisation of the NaOH in the table below, and use them to calculate the NaOH concentration: NaOH standardisation Titration volumes (mL) … optimeyes roseville michigan
What happens when sodium benzoate is heated with soda lime?
Weblayer can then be acidified and subsequently extracted with ether to obtain benzoic acid, separated from the naphthalene and aniline (figure 3). The ether layer containing benzoic acid can be evaporated off to provide the solid benzoic acid. Figure 3. Acidification of the Basic Solution naphthalene OH O benzoic acid NH2 aniline in ether NaOH ... Webextracted with several portions of aqueous NaOH solution. This converts the benzoic acid into its water-soluble sodium salt, which is now contained in the basic aqueous layer. Several NaOH extractions are done to help ensure complete removal of benzoic acid from the ether layer, and the other organic by-products. Note that you must retain WebThe correct option is B Formation of benzene take place. Sodium salt of Benzoic acid on heating with soda lime (NaOH +CaO) the following decarboxylation reaction takes place resulting in formation of benzene and sodium carbonate.
