Once the sugar is poured into the water, it is stirred. After stirring, the sugar can no longer be seen. Also after stirring, each student tastes the water. They both agree that the water tastes sweet. The weight of the water + glass + sugar is the same as the weight of the glass containing the mixture after the sugar was stirred in.
Sugar - Wikipedia
Syrups made by dissolving granulated sugar in water are sometimes referred to as liquid sugar. A liquid sugar containing 50% sugar and 50% water is called simple syrup. Syrups can also be made by reducing naturally sweet juices such as cane juice, or maple sap. Corn syrup is made by converting corn starch to sugars (mainly maltose and glucose).
10 Chemical Change Examples - Science Trends
Dissolving both sugar and salt into water is the process of dissolving a solid into a liquid, and removing the water enables the recovery of the salt or sugar. Yet despite the similarities, the processes are different, one is a chemical change and the other physical.
3 Ways To Separate Salt From Water - WikiHow
12/1/2022 · Add a few cups of water to the pan and place it on a hot burner. Wait for the water to heat — it doesn't necessarily need to boil, but the hotter it gets, the more quickly it will dissolve the salt. The reason hot water is best for dissolving salt (and other chemicals) has to do with the motion of the molecules making up the water.
