Soda Ash Analysis and Volumetric Analysis of a Carbonate-Bicarbonate Mixture De Guzman‚ Danica Justine R. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila Abstract Titration is a laboratory method in which the endpoint of a reaction is determined quantitatively. In this experiment‚ the amount of soda ash present in a sample was determined and the alkalinity reported as it was titrated using HCl as the titrant. Also‚ the percentage

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

Candy and soda should be banned from schools‚ since they are the main reason ⅓ of American children are overweight or obese. Unhealthy food keeps getting popular day-by-day. Even though soda and candy taste great‚ there are a lot of negative effects that would be going to end up getting to the person who eats an excessive amount of it. For example‚ the person will get obese‚ they have the risk of suffering from certain cancers and chronic diseases such as: diabetes‚ heart disease‚ asthma‚ and high

Cola Explosion When the Mentos come into contact with the Diet Coke‚ a reaction causes the rapid formation of foam. it is concluded that the potassium benzoate‚ aspartame‚ and CO2 gas contained in the Diet Coke‚ in combination with the gelatin and gum arabic ingredients of the Mentos‚ all contribute to the formation of the foam. The structure of the Mentos is the most significant cause of the eruption due to nucleation.MythBusters reported that when fruit-flavored Mentos with a smooth waxy coating

Theory Testing The theory that was being tested was the Diet Coke and Mentos Geyser. My children wanted to try and see if we could make the Diet Coke shoot out of the top of the bottle like the videos that they had watched on Youtube.com. How the experiment works is you open a package of Mentos and drop the entire package in the Diet Coke as fast as possible. The faster the Mentos drops‚ the more forceful the Diet Coke Geyser will shoot. What should happen is the combination

Elephant’s Toothpaste Mix two solutions together and you get an amazing eruption of foam. (Submit Review) Mix two solutions together and you get an amazing eruption of oxygen-filled foam that looks like a giant stream of toothpaste... or elephant toothpaste. The classic reaction is a favorite of chemistry teachers who have access to these chemicals that you will not find around the house.

reaction that usually requires some activation energy‚ such as lighting it with a match. A gas is released: These are usually visible reactions because they will start to bubble. A safe and simple example of this is the reaction between baking soda and vinegar. These two chemicals (sodium bicarbonate and acetic acid) react and release carbon dioxide. A color change occurs: Combining chemicals can change the pigmentation that gives the chemicals color. A change in the pigments will cause

Chemistry is the science of dealing with the compounds‚ elements‚ and molecular structure of matter. Essentially‚ chemistry is the science of examining substances and objects to find out what they’re made of and how the react to different conditions.

With all of your ingredients in your bottle the water and the food coloring have a reaction to the baking soda which then makes a massive explosion. Another part to the explosion is our Diet Coke and Mentos test. That test got really messy very quick. I managed to get a video of it where it explodes and when I squeezed the Coke bottle and it went all over my friend Donnie. We also had a pinata after we were
