Answer:
The concentration of hydronium ions is 0.0155 mol/L
Explanation:
The aqueous solution ionization reaction for nitric acid is as follows;
HNO₃ + H₂O → NO₃⁻ + H₃O⁺
Whereby HNO₃ is a strong acid and it undergoes complete ionization in an aqueous solution
Hence one mole of HNO₃ produces one mole of H₃O⁺ ions
0.0155 mol/L HNO₃ will have 0.0155 moles of H₃O⁺ in one liter of the solution
The concentration of hydronium ions = 0.0155 mol/L.
Answer:
ClO₄⁻
Explanation:
When an ion is hydrated it is surrounded by water molecules, thus, as small is the ion, more molecules may surround it, and it will be more strongly hydrated. In this case, the Cl is small than the S atom, because Cl is from group 17, and S from group 16, and Cl has more valence electrons, which will be more attracted to the nuclei.
So, ClO₄⁻ will be more strongly hydrated.
