Hot water is energy which helps dissolve things if u dont believe me boil some water and then get some cold water put both in a clear glass cup and put food coloring in it i will be right. Actually aspirin has a higher solubility in hot water. Do Flowers Drink Warm Water Faster, Slower, Or At The Same Rate As Cold Water? Which Frozen Liquid Will Melt The Fastest Water,sprite,grape Juice Or Orange Juice? Aspirin 75mg is available in a dispersible form and an enteric-coated form, as you are aware. 14 pts ) Some of the minerals found in rocks dissolve in water as it flows over the rocks Would these minerals dissolve more quickly a . Answer (1 of 1): The solubility of a solute could depend on the temperature of its solvent, the higher the temperature of the solvent (hot water) the faster the solute will dissolve in it. b . The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster. Edit: it may be the pH was 7 for the salt water, see comment below. The solvent can only dissolve the aspirin from the outside in. Results: The cold water took the longest to dissolve the aspirin, tap water is not to cold nor warm to tap water was not the longest or the slowest to dissolve the aspirin because its in the middle. Equipment: Cold water in a clear glass. Chemistry. 200g/100mL at room temperature compared to 500g/100ml at 100 degree C. Sugar will dissolve faster it the water is less saturated. The reason why the smaller pieces of the tablet did dissolve faster than the larger pieces was because once i had broken them into smaller pieces they took up more surface area in the glass , increasing the surface area of a reactant in this case the Alka-seltzer tablets r esults in a faster reaction time as shown in my experiment. Two TBS of salt (one in each glass) Aspirin is only slightly soluble in water and acidic solutions such as is present in the stomach. Another example of this is that coal is pulverized before burned at a coal-fired power plant. AIM: To discover how various common liquids, that we consume, affect how Panadols dissolve. His hypothesis was the Vinegar solution, being acidic would dissolve the fastest. The reason that sugar dissolves more quickly in hot water than in cold water has to do with the kinetic energy of the particles. Add a Candy Cane to each container the same way up. Hypothesis: By placing the Panadol in more acidic drinks, such as coke and juices, the quicker the panadol will dissolve.The faster the tablet dissolves, the quicker it can be observed through the stomach lining and into the bloodstream. Like sugar, salt will also dissolve faster when exposed to heat. Get an answer for 'Why would a bath bomb dissolve faster in boiling water than in ice cold water, room temperature water and warm water?' Name Any ONE Entrepreneurial Venture In Pakistan And Discuss How It Has Used Innovation To Create? This may be the reason why carbonated drinks must be kept in a cold place so the gas molecules will continue to mix in with the liquid. Why ? source : Does aspirin dissolve faster in hot or cold water? This mixes the salt and water faster and makes the salt dissolve faster.

See full answer below. In the dispersible form the aspirin is rapidly absorbed in the stomach, whereas the enteric-coated form is absorbed in the duodenum (just below the stomach) because the special coating prevents it from disintegrating in the acid environment of the stomach. In general, hot water dissolves fewer gases (like oxygen or carbon dioxide) but more solids (like salt or sugar) than cold water does. After the Alka-Seltzer tablet was added to the hot water the tablet should have quickly dissolved, taking some 20 to 30 seconds to do so, depending on the exact temperature. Aim: To find out if the temperature of water affects the speed at which salt dissolves. Was this answer helpful? Ask Your Question Fast! It is only the carboxylic group that is polar. Hypothesis: The salt will dissolve faster is hot water rather than cold. Sugar dissolves more quickly in hot water because the water molecules are moving at a higher rate of speed and break down the sugar more quickly. Aspirin contains polar functional groups which can form hydrogen bonds with polar water molecules. This added movement tends to make the bonds between sucrose molecules easier to overcome. We used pH test strips, and it seemed the vinegar solutions was a pH of about 6, the water 7 as expected, and the salt water 8 or 9. several times. As mentioned earlier, polar solvents are good at dissolving polar solutes. Observe at 5 minute intervals ( can you design a table to record your observations? ) there are no internal stabilizing structures that favor carboxylate group, -COO (-), over carboxylic acid, -COOH group. These processes result in fine powder, which is not particularly soluble: it binds the water and clumps, and it doesn't really look nice. Why Does Sugar Dissolve Faster In Hot Water Than In Cold Water? There is also another difference and that is you can dissolve more sugar in hot the cold water. That expansion allowed more water to be exposed simultaneously to the same amount of aspirin, dissolving it faster.
