How does rate of reaction relate to Alka-Seltzer tablets?
How does SURFACE AREA affect reaction rate? Increasing the surface area of the Alka seltzer tablet by crushing it exposes more H+ and bicarbonate ions in the water, which increases the number of effective collisions that can occur between particles in a shorter amount of time.
What things affect the rate of Alka-Seltzer chemical reaction?
The factors temperature, concentration, and particle size altered the chemical reaction rate of Alka-Seltzer and water. The higher the temperature, the faster the reaction because the molecules move around faster and therefore there are more collisions between the reactants.
What is the reaction of Alka-Seltzer and water?
Alka-Seltzer and other fizzing tablets produce carbon dioxide-filled bubbles when placed in water. As the carbon dioxide is produced, you can see bubbles grow and float to the surface of the water.
What is the relationship between particle size and reaction rate?
Decreasing the size of the particles, which make up a given weight, will increase the number of particles represented by the same weight. Smaller particle size results in an increase in the rate of reaction because the surface area of the reactant has been increased.
How would the rate of reaction be affected if you first crushed the Alka-Seltzer tablet before adding it to the water?
Students will time the difference in reaction rates between a whole Alka Seltzer tablet and a crushed Alka Seltzer tablet. Since the crushed tablet exposes more particles to the reacting water it will react at a faster rate.
Does pressure affect the rate at which the Alka-Seltzer dissolves?
If any of the products or reactants involved in a chemical reaction are gases, the rate of reaction will decrease as pressure on the system is increased. When water reacts with Alka-Seltzer, one of the products of the reaction is carbon dioxide gas.
What factors affect how fast Alka-Seltzer reacts with water?
In general, an increase in temperature increases the rate of the reaction. Therefore, students are able to demonstrate this relationship using water of different temperatures. When a seltzer tablet is dropped in hot water, the reaction will occur more quickly than when one is dropped in room-temperature water.
How does temperature affect the rate of reaction?
Increasing the temperature increases the average speed of the reactant molecules. As more molecules move faster, the number of molecules moving fast enough to react increases, which results in faster formation of products.
How do you speed up an Alka-Seltzer reaction?
When seltzer tablets are placed in water, a chemical reaction takes place. The chemical reaction that results will take place faster in hot water than in cold water because temperature increases the rate of the reaction.
Which reaction is faster Why?
Reactions in phases that easily mix, such as gases and liquids, occur much faster than reactions between solids. The extent of mixing of the reactants influences the frequency of molecular collisions – if reactants are more thoroughly mixed, the molecules will collide more often and thus react faster.
What are the dangers of Alka Seltzer?
This medicine may raise the chance of severe and sometimes deadly stomach or bowel problems like ulcers or bleeding. The risk is greater in older people, and in people who have had stomach or bowel ulcers or bleeding before. These problems may occur without warning signs. You may bleed more easily. Be careful and avoid injury.
Can Alka Seltzer kill you?
If you are thinking of giving your cat a tablet of Alka-Seltzer, then the answer is nothing but a big: NO! Alka-Seltzer contains aspirin as its main component which can disturb your cat’s digestive system to an extensive level. A cat can easily be overdosed and as mentioned above, too much Alka-Seltzer in a cat’s stomach can lead to its death.
Why does Alka Seltzer react faster in hot water?
The bicarbonate acts as a base and reacts with the citric acid to keep the acid and base properties neutralized, producing a salt. Hypothesis. We predict that an alka-seltzer tablet will dissolve faster in hot water than in cold water because hot water causes molecules to speed up in a reaction.
What water does Alka Seltzer react in faster?
One thing learned from the online video is that Alka-Seltzer dissolves faster in hot water than in cold water. The second thing learned is the reason why the Alka-Seltzer dissolves in hot water faster than in cold water. The reason is because higher temperatures have higher kinetic molecular energy.
