Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. Is dissolving of salt or sugar in water a physical change or chemical change? 1 decade ago. Meaning to say, salt will technically dissolve faster in water because both consist of molecules bound together by ionic bonds, as opposed to the covalent bond in sugar, which is organic.

Gases, on the other hand, do not dissolve as quickly in water when heated. But I too predicted salt to be better at dissolving. Hypothesis: The salt will dissolve faster is hot water rather than cold. … Powered by Create your own unique website with customizable templates. In this experiment, sugar should dissolve faster in solvents than salt does. Anonymous. Timer; Pen and paper to record results. The point of this experiment, in addition to learning whether salt or sugar dissolves faster in various liquids, is to learn how molecules interact in a solution. Answer 3: The kind of salt we eat dissolve more quickly in room temperature water than in cold water. 2) The bond between the atoms of the solvent are similar to the bonds in that of the solute. Why tap water boil faster than sugar water/? Flour doesn't dissolve in water. Salt is soluble in water too. As you saw in the preceding illustration, the water molecules take up most of the room in the container. Equipment: Cold water in a clear glass. Why does cold water makes salt crystal beter than hot water? Ionic bonds are electrically charged atoms that are attracted to eachother. This allows for more water molecules to surround a single particle, pulling it into solution faster. I can t really explain the results yet- I m guessing that Hammad is right when he said that sugar molecules have weaker bonds between themselves than salt. For older children. When you mix sugar with water, the sugar dissolves to make a transparent solution. However, the results I received from the experiment were not what I expected. Hi I need help with two quick questions... thanks in advance.... With the same type of agitation and at the same temperature, why would sugar disolve in water much faster then salt does? Two TBS of salt (one in each glass) Spoon for stirring. A short and simple experiment that I had to do for science. As they move faster , they come into contact with the sugar more often, causing it to dissolve faster . The control in your experiment will be water. quick help!!! Sugar is moderately soluble, but less of it will dissolve. Post to Twitter . Pepper and sand are insoluble, they will not dissolve even in hot water. Substances that dissolve in water are called soluble substances. Which will dissolve faster in water salt sugar flour or pepper .
