| 21. | Concentrated solutions ( much more concentrated than over-the-counter medical products ) are even more dangerous because they corrode tissues.
|
| 22. | Nasal glands remove excess salt from seawater consumed by the petrel as a concentrated solution excreted through the nostrils.
|
| 23. | In particular, at room temperature the concentrated solution with the density of 4.25 g / cm 3 is amber-yellow.
|
| 24. | In concentrated solution, the additional HF causes the ion pair to dissociate with formation of the hydrogen-bonded hydrogen difluoride ion.
|
| 25. | However, careful reading of our acetic acid article will indicate that similarly concentrated solutions of ethanoic acid are also hazardous.
|
| 26. | The less concentrated brine required more time to evaporate and the total yield was less than a more highly concentrated solution.
|
| 27. | This can be calculated for dilute solutions using the Debye H�ckel equation; for more concentrated solutions other approximations must be used.
|
| 28. | In some areas, they are spraying buildings with concentrated solutions of the chemical to reduce the risk of disease, Prescott said.
|
| 29. | A concentrated solution of this strong electrolyte has a lower vapor pressure than that of pure water at the same temperature.
|
| 30. | It is prepared by treating a concentrated solution of arsenic acid with ammonia, resulting in precipitation of colorless crystals of the trihydrate.
