Initial moles of sodium acetate = acetic acid = 1 m * 1 L = 1 moles
[ acetate ] after adding NaOH = 1 mol+ 0.55 mol = 1.55 M
[acetic acid] after adding NaOH = 1 mol - 0.55 mol = 0.45 M
According to Handerson-Hasselblach equation:
PH = Pka + ㏒ [ acetate]/[acetic acid]
when Pka = 4.74
so, by substitution:
∴PH = 4.74 + ㏒[1.55/0.45]
∴ PH = 5.28
Answer:
is a simple, safe, and easy-to-create electrode
Explanation:
the hydrogen electrode is based on the redox half-cell:
building:
1) Platinium electrode
2) hydrogen pumping
3) acid solution [H+] = 1M
4) siphon to prevent oxygen presence
5) galvanic cell connector
this electrode is used as the basis for standard potential tables
Constitutional isomers<span> are compounds that have the same molecular formula but different connectivity.
To determine whether two molecules are </span>constitutional isomers<span>, just count the number of each atom in both molecules and see how the atoms are arranged.
If both molecules have the same count for </span>all<span> of the different atoms, </span>and<span> the atoms are arranged in different ways (i.e. their </span>connectivity<span> is different), then they will be constitutional isomers.
In this case C2H5Cl will not have any constitutional isomer. Because you can attach the Cl on first carbon or second carbon, both structure will be same. There will only exist one structure. Figure is attached</span>
A Polyatomic ion is a charged chemical species that consists of two or more atoms chemically bonded.
<span>If one of the impurities in diesel fuel has the formula c2h6s, then the products that will form would be carbon dioxide, water and sulfur dioxide. The balanced chemical reaction would be as follows:
</span>C2H6S(l)<span> + 9/2O2(g) = 2CO2(g) + 3H2O(v) + SO2(g)
</span>
Hope this answers the question.
