What can make a large block of sugar dissolve faster in water?

Answer 1

Temperate (Heat): Hotter temperature of solvent (water) speeds up movement of its particles, which would make them collide with the solute (sugar crystals) and break it apart faster.

Stirring: Vigorous stirring helps spread the solute (sugar) evenly in the solvent (water), which would speed up dissolving because the stirring gave the water quicker access to all of the sugar crystals.

Increase Surface Area (small sugar crystals): Make sure that the solute is as fine as possible before adding solvent. This adds more surface area which exposes more solute (sugar) to the solvent (water), so it dissolves faster and more efficiently than larger pieces of solute.

Answer 2

• Sugar has a similar bonding to water, therefore, it interacts with and can be supported by the bonding in water - hydrogen bonding which is a type of polar bonding.
• A small grain size results in a high surface area which speeds up the solution.
• An increase in the temperature of the water will increase the rate of solution of the sugar.
• The larger the volume of water in comparison to the mass of sugar will increase the rate of solution.

Answer 3

If you add a whole bunch of something else to the glass of water before you put the sugar in it...the sugar will just sit there in a pile.

This is called the saturation point.

Below is what is called an Analogy:

Pure water is like a big parking lot with only 1 car in every 10 parking spots. If you put a bunch of salt cars in the left over parking spots then there wont be any room for sugar cars to park. Sugar will just pile up at the bottom of the water with no where to go.

Temperature will also effect how fast sugar will disolve. When wqater gets hot the water cars dont stay parked they drive around all over and will bang into each other like a demolition derby. When you add sugar cars into the lot then they will smash around even more until there are so many cars that there is no more room in the parking lot. WHen the water cools down, all of the water cars will push and squeeze around back into there 1 in every 10 parking spots and the sugar cars will also smash and squeeze back into the regular parking spots. All the rest of the sugar cars have to leave the parking lot and they fall to the bottom of the glass.

When you heat a liqiud the Saturation point (number of non water cars in the parking lot) increases.

Of course if you just shake and stir the water in the glass it will also bang all of the water and sugar cars around like before but it still wont let as many cars in the parking lot like heating the water does.

Another way is to take your water way up high on a mountain. The lower air preasure makes the size of the parking lot bigger by a little bit.

Answer 4

Heat the water and mix vigorously then the sugar will dissolve faster.

Answer 5

Higher water temp, more finely ground sugar, and stirring will all increase the rate of dissolution.

Answer 6

Reducing the temperature would be one way, or reducing the pressure.

Answer 7

Sugar doesn't dissolve completely because it is an organic compound. However, it can break down into its simplest form most quickly in hot water because it creates the most kinetic energy.
