What do you expect to observe when a solution of potassium nitrate saturated at 343k or 70 degree celsius is cooled to room temperature?
Well, isn't that just a happy little question! When you cool a saturated solution of potassium nitrate from 70 degrees Celsius to room temperature, you can expect to see some of the potassium nitrate start to come out of the solution and form crystals. It's like nature's way of showing us how beautiful and orderly things can be when they slow down and cool off. Just like painting a serene winter scene, the crystals will slowly appear and bring a sense of peace and tranquility to the solution.
Why do the crystals appear when the solution is cooled?
When a solution is cooled, the solubility of the solute decreases, causing the excess solute molecules to come out of the solution and form crystals. This process is known as crystallization. Cooling the solution reduces the kinetic energy of the molecules, making it easier for them to come together and form a solid crystal lattice.
Why there appear to be differences in retention factor values under saturated and unsaturated conditions during TLC analysis?
Retention factor values can differ under saturated and unsaturated conditions in TLC analysis due to differences in the strength of interactions between the stationary phase and the analytes. In saturated conditions, where the stationary phase is fully occupied, analytes may have weaker interactions and thus elute faster, resulting in lower retention factor values. Conversely, under unsaturated conditions, analytes can form stronger interactions with the stationary phase, leading to longer retention times and higher retention factor values.
What mineral appears in transparent hexagonal crystals?
Quartz can appear in transparent hexagonal crystals.
What does the mixture of salt and water look like?
When salt is mixed with water, the salt crystals dissolve in the water, making the solution appear clear. You won't see solid salt particles floating in the water anymore.
What is the difference between saturated and unsaturated colors?
Saturated colors are vivid and intense, while unsaturated colors are more muted and subtle. Saturated colors have a higher level of purity and brightness, while unsaturated colors have a lower level of intensity and appear more washed out.

What will appear at the bottom of the solution if you lower the temperature if a saturated solution?
If you lower the temperature of a saturated solution, some of the solute may begin to precipitate out of the solution and settle at the bottom. This is because solubility generally decreases with decreasing temperature, so the excess solute that was dissolved at the higher temperature will no longer be able to remain in solution at the lower temperature.

Is a Solution that holds more solute than it normally would be saturated solution?
No, if it holds MORE than it should it is supersaturated.The term supersaturation refers to a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.Saturation is the point at which a solution of a substance can dissolve no more of that substance (under normal circumstances) and additional amounts of it will appear as a precipitate.

What type of bonds appear in unsaturated fatty acids?
In unsaturated fatty acids, double bonds appear between carbon atoms. These double bonds create kinks in the carbon chain, which disrupts the ability of the molecules to pack tightly together. This is why unsaturated fats are typically liquid at room temperature.
What does amorphous sediment mean?
Amorphous Crystals ¤Amorphous urates are found in acid urine. These crystals may appear pink on gross analysis and yellow microscopically (Figure 2-12). These crystals appear as granules in the urine sediment. Amorphous phosphates are found in alkaline urine. These granules are colorless microscopically and also appear granular when viewed microscopically. Occasionally amorphous material may appear in clumps or masses. It may be difficult to distinguish amorphous crystals from bacteria since they may be of the same size when viewed microscopically. However, amorphous crystals are soluble in opposing acid or alkaline solution; bacteria will not. Amorphous urates will also dissolve when heated. cited from: http://www.tetonnm.com/pics/MESSamplePages/1-893441-10-5.pdf retrieved 4/11/2009

True or false a picture painted with less saturated colors will appear grey or dull?
True
Is iron chloride is a compound?
It depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple. they also change colour depending on whether they are dry crystals (yellow) or have water attached (green).
