Bloating and Cramping Expect initial bowel movements to be composed of firm to semi-firm stools. The unknown started as and remained a clear, colorless liquid. Two clear colorless solutions were combined. Besides, in Reaction E, when a transparent colorless liquid ( Pb (NO3)2) and a clear yellow liquid(K ₂ CrO ₄ ) were mixed, we got a clear colorless solution with a yellow solid PbCrO4. As the colon takes up more liquid and expels more waste, the stools will be liquid in consistency and clear in color. This is due to the reason that in case of coloured solutions lower meniscus is not visible clearly. My husband has taken the green one and he does not like it, he likes the clear one better, they are by different manufacturers. Water is a common example of a liquid that forms a concave meniscus. (names, Lactulose, Enulose,) The "Vanishing Valentine" uses a resazurin solution that starts out blue. The bowels are meant to change after drinking the solution. Many solutions used in separatory funnels are fairly dilute, so the density of the solution is approximately the same as the density of the solvent. To sum this up, a solution will be transparent, meaning you can see through it, but it is not always going to be colorless. The solution is homogeneous and does not settle out. ==>> For more on Mixtures (Solutions, Suspensions, Emulsions, Colloids ) In summary: A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. Try the Hot and Cold Valentine Reaction Most people would assume that urine that is completely clear with no color at all would be a good thing. The student observed that the temperature changed from 25 •C to 23 •C when the solutions were combined and that a white substance rapidly formed and settled to the bottom of the container. Clear urine is a sign of good hydration and a healthy urinary tract. There is a detectable odor, but it does not lend itself to identifying the unknown. Keep drinking water or other clear liquids to aid in the cleansing. Firstly, a colored solution does NOT color what you look at through it - It filters out (ie, absorbs) all the other colors of light passing through it. No crystallization was ever detected in the melting point determination. However, if they consistently notice clear urine and also have extreme or unusual thirst, it is best to speak to a doctor. The liquid again becomes colorless and can be cycled through the clear-to-pink cycle multiple times. The unknown is a clear, colorless liquid. Q. So, you might be surprised to learn that clear, colorless urine can sometimes be a symptom of certain health issues. Maybe tell your pharmacist the one he likes and they will accommodate. Clear urine with a tint of yellow color is usually a sign of healthy urine and that you are well-hydrated. 2. A solution cannot be filtered but can be separated using the process of distillation. In some cases, the molecules of a liquid are more attracted to each other than the sides of the container, the liquid will pull away from the side of the container and form an upward curve, or convex meniscus. For example, in reaction C, when mixing a clear colorless liquid (NaCl) plus a clear and colorless liquid (AgNO ₃), we got a white cloudy solid (AgCl). Most liquids form this kind of meniscus. When the flask is swirled, the contents change to pink.

After a matter of minutes, this solution becomes clear.
