It is the sodium salt of acetic acid and is commonly used for pH regulation and as a food additive. It is also used in experiments to make hot ice, as it has the particularity of crystallising instantaneously in an exothermic reaction in certain situations.<\/p>\n<h2 class=\"productdescription\">IDENTIFICATION AND PROPERTIES SODIUM ACETATE<\/h2>\n<p><strong>Name:<\/strong> Sodium acetate<br \/>\n<strong>Synonyms:<\/strong> Acetic acid, sodium salt, trihydrate.<br \/>\n<strong>Chemical Formula<\/strong>: CH3COONa 3H2O<br \/>\n<strong>CAS:<\/strong> 6131-90-4<br \/>\n<strong>EC:<\/strong> 204-823-8<\/p>\n<ul>\n<li>Appearance: Solid<\/li>\n<li>Colour: White<\/li>\n<li>Odour: Odourless<\/li>\n<li>pH: 8.9 (0.1m solution)<\/li>\n<li>Boiling point: 122.8 \u00baC<\/li>\n<li>Freezing\/melting point: 57.8 \u00baC<\/li>\n<li>Solubility: Soluble in water<\/li>\n<li>Specific gravity\/density: 1.45<\/li>\n<li>Molecular weight: 136.08<\/li>\n<\/ul>\n<h2>USES OF SODIUM ACETATE TRIHYDRATE<\/h2>\n<ul>\n<li>Sodium acetate is used in the textile industry as it removes sulphuric acid residues.<\/li>\n<li>In the textile industry it also acts as a photoresist especially when aniline based dyes are involved.<\/li>\n<li>The solution of acetic acid and sodium acetate acts as a buffer solution to maintain the pH at certain values.<\/li>\n<li>It is also used in thermal hand warmer bags. In bags in which the contents harden when pressed by heating for a certain period of time.<\/li>\n<\/ul>\n<h2><strong>INSTANT CRYSTALLISATION OF SODIUM ACETATE<\/strong><\/h2>\n<p>Sodium acetate has the peculiarity of crystallising instantly in a saturated solution. To achieve this instantaneous crystallisation, it is necessary to dissolve 200g of product in 50ml of water and heat it while dissolving. As it is a hydrated product, when heated, the product itself releases water.<\/p>\n<p>It is then allowed to cool. Once it has cooled to below 40\u00ba, when a disturbance is introduced into the solution, it will crystallise instantaneously.<\/p>\n<div style=\"width: 640px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-813-1\" width=\"640\" height=\"640\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-sodio-instagram-alquera.mp4?_=1\" \/><a href=\"https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-sodio-instagram-alquera.mp4\">https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-sodio-instagram-alquera.mp4<\/a><\/video><\/div>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-38474\" src=\"https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-de-sodio-cristalizacion-instantanea-300x186.jpg\" alt=\"acetato de sodio cristalizaci\u00f3n\" width=\"373\" height=\"231\" srcset=\"https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-de-sodio-cristalizacion-instantanea-300x186.jpg 300w, https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-de-sodio-cristalizacion-instantanea-600x373.jpg 600w, https:\/\/www.alquera.com\/wp-content\/uploads\/2017\/06\/acetato-de-sodio-cristalizacion-instantanea.jpg 750w\" sizes=\"auto, (max-width: 373px) 100vw, 373px\" \/><\/p>\n<p>As it crystallises instantaneously, it heats up.
