Question

You have a cup of water and an alka-seltzer tablet. You want to dissolve the alka-seltzer tablet at a faster rate than normal. Think of a method of how you could speed up the reaction.

Answer 1

To dissolve an alka-seltzer tablet at a faster rate, you can break the tablet into smaller pieces, agitate the solution, or increase the temperature of the water.

Step-by-step explanation:

To dissolve an alka-seltzer tablet at a faster rate than normal, there are a few methods you can try:

1. Break the tablet into smaller pieces: Breaking the tablet into smaller pieces will increase the surface area of the tablet, allowing more water molecules to come into contact with the tablet and speeding up the dissolution process.
2. Agitate the solution: Stirring or agitating the solution will help bring fresh solvent molecules into contact with the solute, increasing the rate of dissolution. You can try stirring the water and tablet mixture gently with a spoon.
3. Increase the temperature of the water: Heating up the water will increase the energy of the water molecules, leading to more frequent and energetic collisions between the solvent molecules and the tablet particles. This will enhance the rate of dissolution.
