What measures can be taken to decrease the relative supersaturation during a precipitation?

Short Answer

Expert verified

The measures to be taken to decrease the relative supersaturation during a precipitation

  1. Slow addition

  2. Homogenous solution

  3. Dilute reagents

  4. Increased temperature

Step by step solution

01

Definition

It is an analytical technique that uses a precipitation reaction to separate ions from a solution. The chemical that is added to cause the precipitation is called the precipitant or precipitating agent

02

Measures to be taken to decrease the Supersaturation

1. Slow addition of precipitating agent and mixing during addition

2. Precipitate forms homogenous solution 鈥� precipitating agent in this case is synthesized in the solution and isn鈥檛 added mechanically.

3. Precipitating using dilute reagents

4. Increased temperature 鈥� solubility is increased.

What does the designation 200/400mesh mean on a bottle of chromatography stationary phase? What is the size range of such particles? Which particles are smaller,100/200or 200-400mesh?

(a) Figure 1-1 shows a peak O3concentration of 13mPain the stratosphere. Figure 1-3 shows a peak concentration of O3 of 39ppbat ground level at one particular location. To compare these concentrations, convertto pressure in. Which concentration is higher? To convert 39ppb to, assume that atmospheric pressure at the surface of the Earth is 1 bar =105Pa. If atmospheric pressure is 1 bar, then a concentration ofis.

(b) The pressure of the atmosphere at 16kmaltitude in the stratosphere is 9.6kPa. The peak pressure O3 ofat this altitude in the stratosphere in Figure 1-1 is 19mPa. Convert the pressure of 19mPa toppb when the atmospheric pressure is 9.6kPa
