What else can I help you with?
How can sue make some pure dry copper chloride crystals fro the mixture in the beaker?
Sue can heat the mixture in the beaker to evaporate the water and leave only the pure dry copper chloride crystals behind. The crystals can then be filtered out and dried to remove any remaining water.
How do you obtain copper from a mixture of powered copper and sodium chloride?
Put the mixture in a beaker then add some water. Stir until the sodium chloride is completely dissolved. Filter the water to get copper oxide as your residue. Then strongly heat the water till it evaporates, to form crystals of sodium chloride.
When sodium chloride and distilled water solution is evaporated what is left?
When a sodium chloride and distilled water solution is evaporated, the water evaporates, leaving behind solid sodium chloride crystals. The crystals are the original salt that was dissolved in the water.
Will damp cobalt chloride turn back blue once dried?
Solid Cobalt chloride crystals are pink when hydrated with water. If you heat the crystal, the water of crystallisation in the crystals will evaporate, leaving you with solid anhydrous cobalt chloride crystals which are blue in colour.
How would you recover crystals of sodium chloride from sodium chloride solution?
Evaporate the water.
Do halite crystals form when a solution of water and salt dissolves?
After the evaporation of water sodium chloride crystals are present.
Ken had a beaker containing 54g of potassium chloride dissolved in 100cm3 of water at 90 degrees. he cooled the solution to 40 degrees. what would he see as the solutio cooled to 40 degrees?
As Ken cooled the potassium chloride solution from 90 degrees to 40 degrees, he would likely observe crystallization occurring. This is because the solubility of potassium chloride decreases with temperature, leading to the formation of solid crystals as the solution becomes supersaturated. He may see white crystals forming at the bottom of the beaker or floating in the solution as the solute precipitates out.
What happend to the sodium chloride crystals when added to 5ml of water?
water molecule will splits sodium chloride to sodium ions and chloride ions via hydrogen bonding.
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.
When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
What method can be used to extract large pure sodium chloride crystals from sea water?
Evaporating the water sodium chloride is obtained.
What happens when you heat salted water?
Water is evaporated and sodium chloride crystals are obtained.
