8m of hydrogen will react with 1 mol of sulfur.
We have been given the OH⁻ ion concentration, we can calculate the pOH concentration.
pOH = -log [OH⁻]
pOH = - log (5.5 x 10⁻⁵ M)
pOH = 4.26
we can then calculate the pH value
pH + pOH = 14
pH = 14 - 4.26
pH = 9.74
since pH > 7 the solution is basic.
by knowing the pH value, we can calculate the H₃O⁺ concentration
pH = - log[H₃O⁺]
[H₃O⁺] = antilog (-pH) = antilog (-9.74)
[H₃O⁺] = 1.82 x 10⁻¹⁰ M
