1. The Tums tablet is insoluble in water. The water turns foggy when the Tums tablet is added. The particles of the tablet are suspended in the water‚ therefore the water appeared foggy and opaque. The Alka-Seltzer is soluble in water. The ingredients of Alka-Seltzer and the water react together to produce gas‚ thus bubbles formed in the solution. Whereas‚ the Rolaids tablet did not dissolve in water. The powder remained afloat on the surface of the water. Unlike the Tums tablet‚ Rolaids does not

6.05 Logan Hotaling Materials Needed: 1. Alka-Seltzer 2. Glass 3. Water 4. Timer Procedure: 1. First you need to fill a glass up with 8oz of water and have it be 25 degrees Celsius. 2. Then you drop the Alka-Seltzer in the water and time how long it takes it to dissolve in the water. 3. Then we need to make the temperature go up then we need to drop the Alka-Seltzer in the water again and see how long it takes it to dissolve with the new temperature. 4. Now

Theory Does surface area affect dissolving of Alka-Seltzer tablets? Materials: 1. solo cups 2. Alka-Seltzer tablets 3. Timer 4. Measuring Cup 5. Thermometer Procedures: 1. I placed out two of my solo cups on the counter 2. Then I put 1 cup of room temperature water into each cup. 3. Then put one Alka-Seltzer Tablet in one cup and time it until it dissolves completely. 4. In the second cup I put in a crushed up Alka- Seltzer tablet and timed it until it dissolved. 5. Repeat steps

INTRODUCTION: In this lab I will try to see in what an Alka-Seltzer tablet will dissolve fastest in. I need to figure out if the Alka-Seltzer tablet will dissolve slowest or fastest in tap water‚ warm water‚ cold water‚ salt water‚ or acidic water. In this lab I wall develop and test a hypothesis‚ analyze data and draw a conclusion. In this experiment I will find out that in a type of water the Alka-Seltzer will dissolve faster and slower. Alka-Seltzer is one of the world’s best known antacids. Its main

effect of temperature on the rate of a chemical reaction by using Alka-Seltzer tablets and different temperatures of water. It is hypothesized that the Alka-Seltzer tablet will dissolve the fastest in the Hot Tap Water because of the higher temperature. The Effect of Temperature on a Chemical Reaction? The purpose of this experiment is to determine if the scientist can conclude in which temperature of water an Alka-Seltzer tablet has the fastest reaction time. The scientist will measure the

Chemistry 101 Lab 7 Determination of % NaHCO3 in Alka Seltzer Tablets Names ____________________________and ___________________________ Date ____________________________ Objectives: (1) To determine the amount of NaHCO3 in Alka Seltzer tablets by observing the amount of CO2 produced from the acid-base reaction of HCO3- with acetic acid (in vinegar). (2) To study the concept of limiting reactant. Background: Alka Seltzer is an effervescent tablet that contains aspirin

If the rate at which the Alka Seltzer tablet dissolves is related to the temperature‚ then the temperature will affect the rate at which the tablet dissolves. 2. If the rate at which the Alka Seltzer tablet dissolves is related to the surface area‚ then the surface area will affect the rate at which the Alka Seltzer tablet dissolves. 3. If the rate at which Alka Seltzer tablet dissolves is related to the catalyst‚ then the catalyst will affect the

about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister with the Alka-Seltzer tablet‚ the slower the reaction will be because adding more water will mean there will be more water to disperse the Alka-Seltzer (basically this will decrease the concentration of the Alka-Seltzer in water).
