Today in chemicals we did an experiment that involves mixing & dissolving, But we must know what mixing & dissolving is. So basically two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is a substance that can be dissolved (sugar) and the solvent is the one doing the dissolving (water)
On to the experiment we had 2 beakers (one large/one small) one was to store the sugar and the other one was to hold cold water and hot water, also we had a spatula to put the sugar in the beaker. Our aim was to see how fast the sugar will dissolve into the water. Also, a reminder that there are multiple groups doing this experiment as well.
First, we had filled the large beaker with 50ml's of cold water. Then with the spatula, we put sugar in the beaker that was filled with cold water then stirred it. We also had to use a timer as soon as we put the sugar in and until it has fully dissolved we had to stop the timer to get our results. Our result was 59 seconds but the average result for this is 54 seconds. Then we did the same thing but with hot water and it went quicker than usual since the hot water was making the sugar make more space between them, and then our result was 25 seconds but the average time was 29.75 seconds.
We did the same thing again but without stirring the water, and our results for this are 90 seconds also with hot water but the average result was 76.2 seconds. Then we did the same thing again but with cold water and our results were 360 seconds and the average result was 136.8 seconds
