Why are crystalline precipitates more purer than colloidal precipitates?
Colloidal precipitates are made up of colloidal particles which are really small (1 to 100 micrometres). Since they are small, they have a lot of surface area which promotes surface adsorption. Surface adsorption increases impurities as foreign ions might be present in the counter-ion layer. Crystalline precipitate consists of larger particles, have lesser surface area, thus surface adsorption is less. Hence they are more pure.
Which water requires the greatest amount of salt to float an egg?
There aren't different types of water (unless you count water with different levels of impurities, but in most cases the impurities will have the same effect as the salt, so it is just the purer water that needs more 'added' salt)
What physical state are precipitates when they form?
Precipitates form whenever two insoluble ions are in solution, thereby leaving solution. They can form either gases or solids (usually solids).
What are the impurities found on the surface of magnesium in the formula of magnesium oxide?
impurities such as nitrogen and carbondioxide
What can you say about a solution when Qsp is greater than Ksp?
Precipitates will form
What is the use of filter paper?
Filtering paper id used to separate precipitates or other insoluble impurities from solutions.
What kind of impurities remain in river water?
The kinds of impurities that remain in river water include many types of bacteria and heavy metals.
How do you measure impurities in diamonds?
Your question depends on the types of impurities you're measuring. Impurities develop both when the diamond is formed, and after the diamond is formed. For example, if you are measuring visible impurities -- other minerals included within the clear gemstone -- you can measure them with a 10X loupe, and measure them visually. You can read more about both types here: http://en.wikipedia.org/wiki/Diamond_flaws

In the water cycle does evaporated water precipitates at rain or snow?
As both depends on the weather because the four types of precipitation are RAIN, SNOW,SLEET, and HAIL!
Does ammonia has impurities?
Ammonia does not have impurities in it
Why suitable impurities are added to semiconductor depending upon its use?
The idea is that, depending on the impurities added, the semiconductor will be of one of two different types: * n-type, where the current is conducted by electrons, and * p-type, where the current is conducted by holes.
What precipitates all research?
questions
Why do precipitates sometimes not form?
overheating
What are solids that do not dissolve called?
Precipitates
What are the differences between colloidal precipitate and crystalline precipitate?
Crystalline precipitates have less surface area than the colloidal precipitates, therefore they are more pure. Additionally, crystalline precipitates, because they are larger, are more easily separated from the surrounding solution.
Difference between NPN and PNP?
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
