How would you obtain pure crystals of calcium chloride?
To obtain pure crystals of calcium chloride, you can start by dissolving calcium chloride in water to form a saturated solution. Then, allow the solution to cool and evaporate slowly, which will cause calcium chloride crystals to form. Once the crystals have formed, they can be filtered and dried to obtain pure crystal calcium chloride.
What is the procedure of recrystallisation of benzanilide?
To recrystallize benzanilide, you would first dissolve it in a hot solvent (such as ethanol) until it forms a clear solution. Next, slowly cool the solution to allow crystals to form. Filter the crystals, wash them with a cold solvent to remove impurities, and then allow them to dry to obtain pure benzanilide crystals.
What would you do to form a heterogeneous mixture of sugar and salt crystals?
To form a heterogeneous mixture of sugar and salt crystals, you can simply mix the two substances together in a container. The sugar and salt crystals will not dissolve into each other as they have different chemical properties, creating a visible separation in the mixture.
Why cant you heat sugar and water to separate it?
Heating sugar and water will not separate them because sugar dissolves in water to form a homogeneous solution. To separate them, you would need to use a physical method like evaporation to remove the water and obtain the sugar.
Does sugar evaperate?
No, if you want to be sure this isn't a lie, you can mix sugar and water together and leave the mixture out in a bowl for a couple of days then see if there are crystals at the bottom of the bowl. If you did this correctly you should have some crystals there. It's a pretty cool experiment.
What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.

Can sugar crystals grow in vinegar?
No, sugar crystals cannot grow in vinegar because vinegar typically contains acetic acid, which would prevent sugar crystals from forming. Sugar crystals are more likely to grow in a saturated solution of sugar and water.
How would you obtain pure crystals of the salt?
To obtain pure crystals of the salt, you would typically dissolve the salt in a suitable solvent to form a saturated solution. Then, through techniques like filtration, crystallization, and drying, you can separate the pure crystals from impurities and water to obtain the desired product.
Would sugar crystals be physical science?
Sugar crystals are physical objects.
Why is sugar more soluble when agitated?
The agitation moves saturated sugar solution away from the sugar crystals and allows new, purer water next to them. This essentially speeds up diffusion. The same amount of sugar would dissolve whether or not you agitated the solution. The difference is that if you simply left it it would take much longer.
What part of a solution would added sugar be?
Sugar solution would be the solution.Water would be the solvent.Added sugar would be the SOLUTE.
How much sugar is necessary to obtain 50 ml of a 3 percent solution?
To make a 3% solution, you would need 1.5 grams of sugar for every 50 ml of water.
How would you separate rock salt to obtain salt crystals and pure dry sand?
To separate rock salt into salt crystals and pure dry sand, first dissolve the rock salt in water, creating a saltwater solution. Next, filter the mixture to separate the sand, which will remain on the filter paper, from the saltwater solution. Finally, evaporate the water from the saltwater solution to obtain pure salt crystals, leaving behind the dry sand collected from the filtration process.
How would you get back salt from a mixture of sand and salt?
Add water and stirr: salt is soluble, sand not. Filter the solution. On the filter re- main sand, in the solution salt. After repetitive evaporations you can obtain salt as crystals.

Is the sugar solution homogeneous or heterogeneous and why?
Homogeneous is mixed, like stirring sugar into a cup of tea or water. However, if you put one full teaspoon of sugar into 1/4 teaspoon of water, it would not mix completely-- the sugar would remain in a mostly granulated state. Or if you mixed sugar completely into a small amount of water and let the water evaporate, the sugar crystals would begin to fall to the bottom,e.g. separate from the mixture.
