Find the [H+] in an acetic acid solution that has a pH of 5.12
Eva8 [605]
<span>Data:
pH = 5.2
[H+] = ?

Knowing that: (</span><span>Equation to find the pH of a solution)</span>
pH = -log[H+]
<span>
Solving:
</span>pH = -log[H+]
5.2 = - log [H+]
Knowing that the exponential is the opposite operation of the logarithm, then we have:
[H+] = 10^{-5.2}
\boxed{\boxed{[H+] = 6.30*10^{-6}}}\end{array}}\qquad\quad\checkmark

Sodium carbonate can be made by heating sodium bicarbonate: 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) Given that ΔH° = 128.9 kJ/m
Ad libitum [116K]

Answer:

[tex]128^{o}C[/tex]minimum temperature will the reaction become spontaneous.

Explanation:

\Delta G=\Delta H-T \Delta S

From the given,

\Delta G^{o}=33.1

\Delta H^{o}=128.9kJ/mol

Temperature\,change=25+273=98K

33.1=128.9-298 \Delta S

\Delta S=0.322kJ/mol.K

\Delta G=\Delta H-T \Delta S

0=128.9-T(0.322)=401K=218^{o}C

Therefore, 128^{o}Cminimum temperature will the reaction become spontaneous.
