Drugs that can be determined by acid base titration

Chemistry
1 answer:
Sladkaya [172]2 years ago
8 0

Answer:

Explanation:

an acid base tritation is the determination of the corncerntration of an acid or base by exactly neutralizing the acid or base with an acid or base of known concentration. This is always for quantitative analysis of the corncerntration of an unknown acid or base solution.It makes use of the neutralization reaction that occura between acids and base.

Assume the solubility of benzoic acid in ice-cold water is 1.70 g/L and the solubility of benzoic acid in hot water is 68.0 g/L.
lana [24]

Answer:

The volume of water needed to recrystallize 0.700 g of benzoic acid is 10.29 mL.

Explanation:

For the complete recrystalization,

the amount of hot water should be such that, the benzoic acid is completely soluble in it.

As we are given that the solubility of benzoic acid in hot water is 68.0 g/L. Now we have to determine the volume of water is needed to recrystallize 0.700 g of benzoic acid.

we conclude that,

As, 68.0 grams of benzoic acid soluble in 1 L of water.

So, 0.700 grams of benzoic acid soluble in  of water.

The volume of water needed = 0.01029 L = 10.29 mL

conversion used : (1 L = 1000 mL)

Therefore, the volume of water needed to recrystallize 0.700 g of benzoic acid is 10.29 mL.

Why are valence electrons important
koban [17]

Explanation:

The electrons in the outermost shell of an atom are the valence electrons. These electrons are the most loosely held in an atom.

The energy required to remove these electrons are not as great as those of the inner shell electrons.

  • Atoms of some elements show no tendency to combine with other  atoms because they have completely filled outer energy levels.
  • Their outermost shell, valence shell and the electron numbers are complete for them. These are the noble gases.
  • other atoms share or exchange their valence electrons in order to have a stable configuration.
  • The valence electrons are involve in inter-atomic bond formation and interactions
  • Also the distribution of these electrons determines inter-molecular interactions between molecules.
