How is the completeness of separation of the benzoic acid crystals from sodium chloride known with the addition of AgNO3 solution?
Silver Nitrate solution produces a white precipitate in the presence of chloride ion. The equation is AgNO3 + Cl- ----> AgCl(s) .
So if benzoic acid is completely free of sodium chloride there will be no white precipitate. You can go a stage further by weighing an aliquot of benzoic acid crystals and titrating with a known strength silver nitrate solution. By calculation you can then find just exactly how much sodium chloride is left contaminating the benzoic acid.

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 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.
What will happen if a saturated solution of copper chloride is cooled?
If a saturated solution of copper chloride is cooled, the solubility of the compound will decrease, causing excess copper chloride to precipitate out of the solution in the form of solid crystals. This process is known as crystallization.
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 crystals of calcium chloride made from calcium carbonate and dilute hydrochloric acid?
Crystals of calcium chloride can be made from calcium carbonate and dilute hydrochloric acid through a chemical reaction where calcium carbonate reacts with hydrochloric acid to form calcium chloride, carbon dioxide gas, and water. The resulting solution can be further evaporated to allow crystals of calcium chloride to form.
What is the transparency of sodium chloride?
Pure sodium chloride crystals are colorless.
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.
How could a solution of copper chloride and water be separated into starting substances?
The solution of copper chloride and water can be separated by a process called evaporation. By heating the solution, the water will evaporate, leaving behind crystallized copper chloride. These crystals can then be filtered out, resulting in the separation of the copper chloride and water.
What do you mean by chemical gardan?
A chemical garden is an experiment which is performed by the addition of solid metal salts such as copper sulfate or cobalt(II) chloride to an aqueous solution of sodium silicate. This results in formation of plant like forms in minutes to hours. In its original form, the chemical garden involved the introduction of ferrous chloride (FeCl2) crystals into a solution of potassium silicate (K2SiO3). Common salts used in a chemical garden Cobalt(II) chloride crystals - (Purple) Copper(II) sulfate crystals - (Blue) Aluminium potassium sulfate crystals - (White) Chromium(III) chloride crystals - (Green) Nickel(II) sulfate crystals - (Green) Iron(II) sulfate crystals - (Green) Iron(III) chloride crystals - (Orange) The chemical garden relies on the fact that most transition metal silicates are insoluble in water and are coloured.
Does sodium chloride have crystals?
yes it does
Why are Sodium Chloride Crystals cubed shaped?
It is a sodium chloride crystal.
What is the color of sodium chloride?
Crystals of pure sodium chloride are colorless.
Why do salt crystals have lots of salt?
Because these crystals are formed from sodium chloride.
How were sodium chloride crystals discovered?
Sodium chloride is known from prehistoric times.
Is calcium chloride and potassium chloride crystals in a beaker a pure substance?
Calcium chloride and potassium chloride are pure substances.
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.
Why can sodium chloride produce light?
Pure sodium chloride crystals are transparent.
