Examples of precipitation are: 1  As a weather condition: Water (Hail, Rain, Sleet, Snow) falling from the sky. 2  As a chemical reaction: The formation of an insoluble material when two mixtures containing soluble chemicals are mixed (eg: AgNO3 (aq) + KCl (aq) â AgCl (s) + KNO3 (aq)). precipitation solution is just like asking what is a precipitate; it is an insoluble solid compound that forms out of the water solution in an aqueous solution.
The medical term for dilated pupils is mydriasis. Medications or other drugs can also cause the pupil to dilate, either intentionally or as a side effect. For example, eye care professionals often use eye drops that dilate the pupils in order to examine structures at the back of eye, such as the retina. Other medications and illicit drugs that can dilate the pupils include cough and cold medications, decongestants, cocaine, and marijuana.
Best Answer: Generally, dilation of the pupil will last for three to six hours and will primarily affect your near or close up vision.However, it is not uncommon for dilation to last up to 24 hours for some patients depending on the eye drops used to achieve dilation.t varies a lot depending on the drops they used, and the concentration, as well as your own eyes. It could last anywhere from 4 hours to 24 hours...and has been known to last longer in rare cases. The average is 4 to 8 hours though.
