Amount of Water Colin Lee Dr.Cooper Chemistry 12 Introduction: Alka-seltzer contains three active ingredients‚ aspirin‚ sodium hydrogen carbonate and citric acid. It is used for headaches‚ migraines‚ and cold and flu symptoms. Alka-Seltzer is usually taken when dissolved in a glass of water. When placed in water a series of chemical reactions result into Sodium citrate and Sodium acetylsalicylate. The sodium citrate would act as the antacid for stomach pains‚ and the sodium acetylsalicylate

three different temperatures of water on Alka-Seltzer tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds

Alka Seltzer Expirement Research The Expirement that the chemist will be conducting includes the following materials: hot water‚ room tepmerature water‚ cold water‚ and regular Alka Seltzer tablets. Research on Alka Seltzer in previous expirements shows that it dissolves faster in hotter temperatures of water. It also shows in previous expirements that Alka Seltzer dissolves slower in colder temperatures of water rather than hotter temoeratures. Alka Seltzer is an antacid that contains aspirin

mass of NaCO3 in Alka-Seltzer Tablets Alka-Seltzer is an effervescent antacid typically used for pain relief and neutralizing stomach acid to alleviate indigestion. Alka-Seltzer tablets contain Aspirin‚ Citric Acid (CH3COOH)‚ and Sodium Bicarbonate (NaCO3). When the tablet is placed in water it undergoes an acid-base reaction and Carbon Dioxide (CO2) is a byproduct that causes the notorious “Fizz”. The objective of the lab was to measure the % of NaCO3 in an Alka-Seltzer tablet in different measures

The name of the alka seltzer project is named “The Dropouts.” The significance of that name is that the owners of the machine are very close to dropping out school themselves. Ultimately‚ the goal of the machine would be to pop a balloon and to blow out a candle. The goal would be achieved by using the potential energy in the balloon‚ popping it‚ and using the now present kinetic energy‚ which is the air‚ to blow out the flame of the candle. The final products would be a popped balloon and a blown

will make an Alka-Seltzer tablet dissolve faster? My theory is that the Alka-Seltzer will dissolve faster in the warm water and slower in the cold water because the more heat something has the more energy the atoms or molecules in the object get. So in hot water the molecules inside are moving around really fast and have tons of energy to dissolve the tablet while in cold water the molecules are still moving around but at a slower pace therefore taking longer to dissolve the tablet. The materials

Should Tablets Replace Textbooks? Today‚ there is a debate on whether schools should stay with classic textbooks‚ or take a more advanced approach and use tablets as a replacement for all textbooks. Many schools like Carmel are going about having every student own a tablet for class purposes. This is something that Warren Township High School should really consider. Every student at Warren‚ for many reasons‚ should own a tablet. There is no better substitute for textbooks than a tablet. Studies

the experiment is to find out what effect on surface area has for dissolving antacid tablets. The method used is to have crushed up tablets‚ for more surface area‚ and whole tablets‚ less surface area‚ to see which of the two subjects dissolve faster. The results for this experiment have shown up to be: the crushed tablets generally dissolve faster‚ rather than the whole tablets. Introduction The antacid tablet‚ both crushed and whole‚ started off as a solid state. And both after a minimum of
