* Half the amount of Alka-Seltzer: Yes, half the amount of Alka-Seltzer will dissolve faster. This is because there's less solid to dissolve, so the reaction with the water can happen more quickly.
* Half the amount of water: No, Alka-Seltzer will actually dissolve slower in half the amount of water. Think of it this way: the dissolving process involves the Alka-Seltzer tablets reacting with the water. Less water means fewer water molecules to interact with the tablet, slowing down the dissolving process.
In summary:
* Less Alka-Seltzer = Faster dissolving
* Less Water = Slower dissolving
