WebWhat is the pOH of a solution made by adding 0.5×10−4 moles of H2SO4 to enough water to make 1.0 L of solution? Firstly, it is an acid. So let's calculate it's pH first, Now, formula of pH is, pH= -log [H+] Where, [H+] is hydrogen ion concentration (mol/L). Molarity= mole/volume (L)=0.5*10–4moles /1L = 0.5*10–4 mol/L WebJun 23, 2016 · H 2SO4(aq) +2H 2O(l) → 2H 3O+ + SO2− 4. Thus [H 3O+] = 2 ×0.45 ⋅ mol ⋅ L−1 to a first approx. And pH = −log10[0.90] For a better approximation, we need pKa2 for …
