The distillation of sugar solution results in pure sugar. Therefore, we can separate the sugar by the process of distillation to obtain pure crystals. Hence, (A) is the correct option. Note: The sugar can be separated using a process called evaporation.

The sugar would dissolve in water. You could then pour off the solution and wash the remaining sand with a bit more water. Heat the water to evaporate it from the sugar, and the two are separated.

The mixture of sugar-salt solution can be separated by evaporation. If the water is completely evaporated we will get separated sugar from the mixture. If we dissolve the mixture in alcohol we will get the salt separated while sugar will be dissolved in alcohol.

A mixture made of solid particles of different sizes, for example sand and gravel, can be separated by sieving.

For example, a mixture of sugar and water can be separated by using heat. Heat will separate the water and sugar using a process called evaporation. During evaporation liquid water is turned into a gas. After the water is removed, large chunks of sugar are left.

To collect both solute (sugar) and solvent (water): You would remove solid first, then distil solvent. Unless you are starting with a saturated solution, you would need to do a partial distillation to remove some solvent, then crystallise your sugar, then complete the distillation.

if you dissolve sugar in water then boil it, will it come back like salt or will it evaporate with the rest? A: Very little of the sugar should evaporate. Like salt, it will mostly be left behind.

The answer is D. Distilling.

Science of Cooking: Candy-making Stages | Exploratorium. As a sugar syrup is cooked, water boils away, the sugar concentration increases, and the temperature rises. The highest temperature that the sugar syrup reaches tells you what the syrup will be like when it cools.

If you don’t have a candy thermometer, you can use the cold water test in a pinch: Drop a spoonful of hot syrup into cold water, then remove the candy from the water and attempt to bend it. If your syrup has reached the hard-crack stage, it will form brittle strands in the water and crack as you bend it.

Sugar stages

Hard-Crack Stage is a cooking term meaning that a sugar syrup being heated has reached 149 – 154 C (300 – 310 F.) It is a test of how hot a sugar syrup is, and of how much water is left in it. At this point of heating, the sugar concentration in the syrup is 99%.

Step 6: Hard Crack Stage 300 F (150 C) Hard Crack: With a clean spoon, when the syrup dropped into ice water it separates into hard, brittle threads that break when bent. You can actually hear a crack when the syrup hits the cold water.

The difference between a hard ball and soft crack is that at hard ball stage, the sugar forms a firm but pliable ball rather than threads. The difference between soft crack and hard crack is that at the hard crack, the threads will not bend and will simply break if you try to bend them.

Continue boiling, uncovered, not stirring the mixture but shaking the saucepan occasionally to distribute the heat as the mixture turns amber in about 9 minutes, then darker amber as it registers 305 degrees on the thermometer (hard-crack stage ), about 3 minutes longer.

Corn syrup is a common ingredient in many hard candy recipes because it is an invert sugar. Invert sugar inhibits the formation of sugar crystals and provides a smooth texture to hard candy, caramel, and other cooked sweets.

Why is my hard candy soft and sticky? The simple answer is that there is too much moisture in your candy. In hard candy making, it is important to cook all the water out of the sugar/corn syrup/water mixture.
