This phenomenon results from chemical reactions. \u003c\/p\u003e\n\u003ch2\u003eWhat is a chemical reaction?\u003c\/h2\u003e\n\u003cp\u003eWhen two molecules come into contact, they can react with each other depending on their chemical structure. By bonding, they form new molecules. However, not all molecules can react with each other, which is why reactions only occur with certain combinations. This is why an acid can only react with a base by exchanging a hydrogen proton (H+). \u003c\/p\u003e\n\u003cp\u003eThere are many different chemical reactions that vary in type and mechanism. In other words, depending on the atoms involved, the result will differ. In the case of bath bombs, the chemical reaction occurs between citric acid and sodium bicarbonate, which is a base. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eWhen you mix two solutions—an acidic one (pH \u0026lt; 7) with a basic one (pH \u0026gt; 7)—the solution is said to neutralize (the pH then approaches 7); this is known as an acid-base reaction. When citric acid and sodium bicarbonate are mixed, an acid-base reaction occurs that produces carbon dioxide (a gas also known as CO₂), which is what causes the bubbles and foam to appear in your mixture: that’s effervescence!\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe reaction is particularly recognizable by its sound. Once dissolved in water, the chemical reaction releases carbon dioxide (CO2), which not only causes the noise but also propels the pebble or fizzer to the surface of the water. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThis type of reaction is found in a wide variety of products: we use this trick in our fruit juices. Since they’re naturally acidic, we add a little sodium bicarbonate to make them fizz! It’s also used in some recipes to make dough rise, provided the dough also contains a slightly acidic ingredient. The release of gas inside the dough causes it to rise and gives it a light, airy texture after baking. But this mixture is also used in pharmaceuticals—in aspirin tablets—and even in laundry detergent tablets to help them dissolve more quickly. \u003c\/p\u003e\n\u003ch2\u003eIngredients\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003ePut on gloves.\u003c\/li\u003e\n\u003cli\u003eIn a large glass or bowl, measure out 2 measuring spoons (2 x 15 ml) of baking soda (level spoonfuls).\u003c\/li\u003e\n\u003cli\u003eAdd 20 drops of water using a pipette and 30 drops of one of the two scents.\u003c\/li\u003e\n\u003cli\u003eMix well with a small spoon so that all the baking soda is moistened.\u003c\/li\u003e\n\u003cli\u003eHold the “Acid Mix” packet upright.

Be careful to tip the contents of the packet directly into the glass to empty it and prevent the powder from scattering into the air.\u003c\/li\u003e\n\u003cli\u003eIf you want a multicolored, effervescent bath bomb, prepare 2 additional glasses, scoop out the mixture with the measuring spoon, and pour 30 ml into each glass (2 x 15 ml).\u003c\/li\u003e\n\u003cli\u003eAdd your food coloring as you see fit, following the examples in the table. Do not add more than 25 drops of food coloring to prevent excessive fizzing during molding. If this happens, it means the mixture is too wet; it will expand and distort your mold.\u003c\/li\u003e\n\u003cli\u003eTo make white powder, add a maximum of 5 drops of water per 20 ml; water causes more fizzing than food coloring. Stir immediately.

It restores the skin’s pH balance and has antiseptic and anti-inflammatory effects. The acid base mixture consists of citric acid. When mixed with water, citric acid and sodium bicarbonate react to release CO₂: this explains the effervescence phenomenon (see our special kit: The Chemistry of Effervescence—Sentosphère). \u003c\/p\u003e\n\u003cp\u003eCitric acid is mixed with corn and wheat starch. These two starches serve to bind the various powders together to form a compact ball or pebble. Glycerin and sweet almond oil, found in the colorants and fragrances, respectively, work together to improve skin hydration by forming a light film on the skin. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e \u003c\/strong\u003eD\u003cspan style=\"font-family: 'Arial',sans-serif; color: black; mso-themecolor: text1;\"\u003eimensions in cm: 29 x 29 x 6cm\u003co:p\u003e\u003c\/o:p\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: 'Arial',sans-serif; color: black; mso-themecolor: text1;\"\u003eWeight: 0.5 kg\u003co:p\u003e\u003c\/o:p\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Sentosphere","offers":[{"title":"Default Title","offer_id":45592239145136,"sku":"3373910225007","price":59.9,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0105\/9022\/files\/scentosphere-bombes-de-bain-v2-6559855.png?v=1789818495","url":"https:\/\/www.playhao.com\/products\/scentosphere-bombes-de-bain-v2","provider":"playhao - Toy Shop Singapore","version":"1.0","type":"link"}
