Question
Which is the strongest acid?
SO42–
H2SO3
H2SO4
HSO4–
HSO3–
2 Ag(s) + Sn2+(aq) ? 2 Ag+(aq) + Sn(s)
I am not sure the answer is +0.94 or -0.94
Arsenic, As, is
a.an essential element in the human body.
b.toxic because it results in an increase in the production of ATP.
c.toxic because it binds to the sulfhydryl group in proteins and enzymes.
d.used in high concentrations in ancient cosmetics.
e.None of these choices is correct.
Ag+(aq) + e– ? Ag(s) E° = 0.80 V Sn4+(aq) + 2e– ? Sn2+(aq) E° = 0.13 V Sn2+(aq) + 2e– ? Sn(s) E° = –0.14 VExplanation / Answer
Ans 1 : H2SO4
The strength of an acid is dependent on its ability to readily loose proton. Here Sulfuric acid (H2SO4) has two protons , and the loss of first proton is highly favoured .
So H2SO4 is the strongest acid here.
