Why Do Solute To Dissolve
In my experiment, I investigated the question “How does the amount of solute affect the time it takes for the solute to dissolve?” I thought about this question for a very long time and come up with a hypothesis for the investigation was “If the amount of solute increases, then the time for the solute to dissolve will increase. This is because the solute will become more concentrated and it won’t disolve into the solvent as fast. (Sadner, 2008)” Looking at the data I collected, I think that this hypothesis was accepted, because the more solute added, the longer it took to dissolve.
Through graphing the data, it was found that when the amount of solute increases, the time for the solute to dissolve increases. Looking at the averages, the highest is 262 seconds and the lowest is …show more content…
I made sure that there was 200 mL of water each trial. It’s essential for there to be equal amounts of solvent because the solute will take different times to dissolve in different amounts of solvent.

Paragraph 2: What could you improve on? (Do you think if someone repeated your lab they would get identical results? Why not? What are some steps you could take to improve the reliability and repeatability of your results?)
Point: Although most variables were controlled for, the repeatability of this lab could be improved by including the following steps.
Make sure the lab is quiet and distraction free at all times. This is important to the experiment because when a scientist is doing their experiment, the enviroment should have nothing to distract them from their lab, like people, loud noises, cell phones and much more.
This could be improved by telling everyone to be quiet while experiments are occurring and cell phones being put away. People can’t be taken out of the classroom, so it’s best that everyone stays quiet and focused on their own work.
Another area that could be improved is for all items used be the same each
