Answer: Option (d) is the correct answer.
Explanation:
When two or more different substances are mixed together then it results in the formation of a mixture.
Mixture are of two types, that is, homogeneous mixture and heterogeneous mixture.
In homogeneous mixture, the constituent particles are distributed evenly throughout the mixture.
Whereas in heterogeneous mixture, the constituent particles are non-uniformly distributed.
Thus, we can conclude that mixtures are classified based on the distribution of particles in them.
Answer:
b) [bicarbonate]/[carbonic acid] = 9.4
Explanation:
The pH of a buffer system is given by the Henderson-Hasselbach equation:
- pH = pKa + log ([bicarbonate] / [carbonic acid])
Where pka = -log (Ka) = -log(4.2x10⁻⁷) = 6.38
Now we <u>solve for [bicarbonate] / [carbonic acid]</u>:
- 7.35 = 6.38 + log ([bicarbonate] / [carbonic acid])
- 0.97 = log ([bicarbonate] / [carbonic acid])
= [bicarbonate] / [carbonic acid]
- [bicarbonate] / [carbonic acid] = 9.33 ≈ 9.4
So the answer is b).
