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

What factors 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 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

DESIGN LAB Factors Affecting the Solubility of a Solid in a Liquid In this experiment‚ my goal is to determine the affect of temperature in the solubility of a solid in a liquid. Research Question: How does the change in the temperature affects the solubility of a solid in a liquid? Independent variables: Temperature of the Solution Dependent variables: The solubility of the solid substance Controlled Variables: * The pressure of the room. * The mass of zinc chloride

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

The first lab we did was overall fascinating. Each station had something different to offer and revealed results that I would not have guessed. The exercise that profoundly stuck out to me the most was the “water tank‚” lab. The procedure of the lab was to shoot a red laser beam into the tank of water from three different directions. I first shot the laser from above the water surface‚ then from below‚ and finally from the side of the tank. Interestingly enough‚ each direction‚ the laser would bend
