Why is chromatography particularly well suited to the needs of a drug analyst

Chemistry
1 answer:
Zarrin [17]3 years ago
6 0

Chromatography is used in purification. Drugs analysts may use the technique to separate the active molecule in a drug molecule, for efficacy or toxicity analysis, from the other drug components.

Explanation:

Chromatography is used to separate a mixture of different components based on the size of their molecules. In liquid chromatography, the mixture is dissolved in a solvent that acts as the mobile phase and then passed along a stationary phase with different kinds of pores, As the mixture passes through the pores, their different components are separated because they take different times to pass through the stationary phase because of their different rates in passing through the pores.

In gas chromatography, a gas is used as a mobile phase while a liquid is used as the stationary phase.

To what volume (in mL) would you need to dilute 20.0 mL of a 1.40 M solution of LiCN to make a 0.0880 M solution of LiCN?
CaHeK987 [17]

Answer:

To 318.18 mL would you need to dilute 20.0 mL of a 1.40 M solution of LiCN to make a 0.0880 M solution of LiCN

Explanation:

Dilution is the reduction of the concentration of a chemical in a solution and consists simply of adding more solvent.

In a dilution the amount of solute does not vary. But as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

In a solution it is fulfilled:

Ci* Vi = Cf* Vf

where:

  • Ci: initial concentration
  • Vi: initial volume
  • Cf: final concentration
  • Vf: final volume

In this case:

  • Ci= 1.40 M
  • Vi= 20 mL
  • Cf= 0.088 M
  • Vf= ?

Replacing:

1.40 M* 20 mL= 0.088 M* Vf

Solving:

Vf=\frac{1.40 M* 20 mL}{0.088 M}

Vf= 318.18 mL

<u><em>To 318.18 mL would you need to dilute 20.0 mL of a 1.40 M solution of LiCN to make a 0.0880 M solution of LiCN</em></u>

Rank the following substances in order from most soluble in water to least soluble in water: ethane, C2H6; 2-butanol, C4H9OH; po
stealth61 [152]

Answer:

Potassium chloride > Butanol >Propane > Ethane

Explanation:

Water is a polar solvent and it is likely to dissolve polar molecules.

KCl is ionic in nature and is completely polar and the solubility of the salt, potassium chloride is the highest.

Butanol can form hydrogen bonding with the water despite having a carbon chain. Thus, butanol will be at second.

Taking about, ethane and propane, both are non polar and least likely to dissolve in water. But, the extent of the London forces increases with the increase in the molecular weight. So, propane will dissolve faster than ethane.

The order is:

Potassium chloride > Butanol >Propane > Ethane
