Answer:
d. 0.121 M HC2H3O2 and 0.116 M NaC2H3O2
Explanation:
Hello,
In this case, since the pH variation is analyzed via the Henderson-Hasselbach equation:
We can infer that the nearer to 1 the ratio of of the concentration of the base to the concentration of the acid the better the buffering capacity. In such a way, since the sodium acetate is acting as the base and the acetic acid as the acid, we have:
a.
b.
c.
d.
Therefore, the d. solution has the best buffering capacity.
Regards.
Answer:
0.595
Explanation:
Let's consider the decomposition of hydrogen chloride.
2 HCl(g) ⇄ H₂(g) + Cl₂(g)
The pressure equilibrium constant (Kp) is equal to the product of the partial pressure of the products raised to their stoichiometric coefficients divided by the product of the partial pressure of the reactants raised to their stoichiometric coefficients.
Kp = pH₂ × pCl₂ / pHCl²
Kp = 77.9 × 54.4 / 84.4²
Kp = 0.595
