Unsubscribe from Strangel _? 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. When water is heated, the molecules gain energy and, thus, move faster. Gases, on the other hand, do not dissolve as quickly in water when heated. Salt dissolves a little faster in cold water than hot water. The solubility of sugar changes much more than the solubility of salt based on the temperature of the water. 0 1. Salt is a tiny ionic salt NaOH Sucrose is a organic sugar C12H22O11 Water dissociated the NaCl into Na+ and Cl- ions. Which one dissolves faster, Sugar or Salt? Yes or No?

Answer (1 of 8): Casey SerinIf you want to know why sugar dissolves in water before salt, one of the best things for you to do can be to perform an experiment. When you mix sugar with water, the sugar dissolves to make a transparent solution. Like sugar, salt will also dissolve faster when exposed to heat. 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. quick help!!! Ionic bonds are electrically charged atoms that are attracted to eachother. We discovered that sugar does dissolve faster than salt. And as … salt, its ion dissociate more rapidly in water than sugar molecule does. 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. A short and simple experiment that I had to do for science. Why does cold water makes salt crystal beter than hot water? Everything is made of particles which are always moving. How many grams of salt is added before heating the solution? The other liquids in which you dissolve salt and sugar will be the variables. Try it: castor sugar dissolves much faster than coarse ground sugar. Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. The aim of this experiment was to see if salt or sugar dissolves faster in water at 90 degrees. But if you're using dissolving as a general term, then yes, salt would be the fastest. The hotter the water, the faster you can dissolve something in it. For example, when salt is mixed with water it disappears because it dissolves in the water to make salty water. Pepper and sand are insoluble, they will not dissolve even in hot water. Substances that dissolve in water are called soluble substances. Answer 3: The kind of salt we eat dissolve more quickly in room temperature water than in cold water. 98875 people estimated has viewed this website.
