How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?
The vapor pressure of pure water will be higher than that of an aqueous solution of sodium chloride at the same temperature because the presence of sodium chloride reduces the number of water molecules available to evaporate, lowering the vapor pressure of the solution. In other words, the solute particles in the solution interfere with the evaporation of water molecules, resulting in a lower vapor pressure compared to pure water.
What is the gas evolved when ammonium chloride and sodium nitrate is heated together?
The gas evolved when ammonium chloride and sodium nitrate are heated together is nitrogen gas (N2). This reaction results in the decomposition of ammonium chloride and sodium nitrate to form nitrogen gas, water vapor, and sodium chloride.
What is the vapor pressure of KCl?
The vapor pressure of KCl depends on temperature. At room temperature (around 25°C), the vapor pressure of KCl is very low, close to negligible. As the temperature increases, the vapor pressure of KCl also increases, following the general trend for solids.
Light given off by electric discharge through sodium vapor?
The light given by sodium vapor depends on whether it is a low-pressure or high-pressure lighting system. Low pressure sodium lamps produce a yellow-green light and are less-common today, while high-pressure sodium-halogen produces an orange light. Both types of sodium lighting uses the element sodium, which is heated by a current flow until it becomes luminescent.
How do you separate a mixture of iodine solid and sodium chloride?
Well honey, you can separate iodine solid and sodium chloride by sublimation. Just heat up the mixture and the iodine will turn into a gas and leave the sodium chloride behind. Then you can just collect the iodine gas and let it cool down to form solid iodine again. Easy peasy lemon squeezy!

Is sodium chloride volatile?
No, NaCl is not volatile. NaCl lowers vapor pressure of the solution and raises Bpt.
How would one write out liquid water and water vapor and aqueous sodium chloride and solid sodium chloride in chemical equations?
Phases are denoted with (s) (l) or (g) and aqueous solutions are (aq) ex: H2O(g) - water vapor H2O(l) - liquid water NaCl(aq) - aqueous sodium chloride NaCl(s) - solid sodium chloride
Does sodium chloride turns directly to vapour on heating?
No, sodium chloride does not turn directly into vapor when heated. Instead, it undergoes a phase change from a solid to a liquid at its melting point of 801°C and then from a liquid to a gas at its boiling point of 1413°C.
Describe a way to remove sodium chloride?
Sodium chloride can be removed from solution by distillation. Boiling a solution of sodium chloride will cause the water to boil off and the sodium chloride to be left behind. If the water vapor is then condensed, the water obtained will be free of sodium chloride.
What has the author Virgil Bernard Sease written?
Virgil Bernard Sease has written: 'A study of the vapor pressure of aqueous solutions of potassium chloride at 20C ..' -- subject(s): Potassium chloride, Vapor pressure
What is the gas evolved when ammonium chloride and sodium nitrate is heated together?
The gas evolved when ammonium chloride and sodium nitrate are heated together is nitrogen gas (N2). This reaction results in the decomposition of ammonium chloride and sodium nitrate to form nitrogen gas, water vapor, and sodium chloride.
What is the method used for separating camphor and sodium chloride?
Camphor and sodium chloride can be separated by sublimation. When camphor is heated, it sublimes, meaning it changes from a solid directly to a vapor without passing through a liquid phase, and can be collected separately from the remaining sodium chloride.
How would one write out liquid water water vapor aqueous sodium chloride and solid sodium chloride in chemical equations?
Your question is not so clear; but: - liquid water - (H2O)l - water vapour- (H2O)g - sodium chloride as a solid - (NaCl)s
What solutes is most effective in lowering the vapor pressure of water MgCl2 CCl4 NaCl AlCl3?
NaCl (sodium chloride) is the most effective solute in lowering the vapor pressure of water. This is because NaCl dissociates into ions when dissolved in water, resulting in a greater number of particles in the solution compared to the other solutes listed. More particles in the solution lead to a greater decrease in vapor pressure.
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
How do you write a plan about how to separate sulfur from sodium chloride?
To separate sulfur from sodium chloride, you can use a process called fractional distillation because sulfur has a significantly higher boiling point compared to sodium chloride. First, heat the mixture gradually until the sulfur evaporates. Then, collect the condensed sulfur vapor as it cools back into a solid form, leaving behind the sodium chloride.
