WebSince 3 % 3 \% 3% of the weak acid dissociated, 3 % 3 \% 3% of the weak acid's concentration also resulted to H 3 O + H_3O^+ H 3 O +. [H 3 O +] = [H A] × 0.03 = 0.20 M × 0.03 [H 3 O +] = 6.0 × 1 0 − 3 \begin{align} [H_3O^+] &= [HA] \times 0.03 \\ &= 0.20 \ M \times 0.03 \\ [H_3O^+] &= \boxed{6.0 \times 10^{-3}} \end{align} [H 3 O +] [H 3 O ...

Web1 day ago · To facilitate easy cleaning through digestion and evaporation during sample concentration and determination, HCl, NH 3 ·H 2 O, NH 4 Cl and NH 4 HCO 3 aqueous solution were selected as the catholyte. In accordance with the results of our previous preliminary experiment, the electrolyte concentration was set at 0.1 mol/L [16].To … WebHCl is a much stronger acid than the H 3 O + ion. This means that H 2 O is a stronger base than the Cl-ion.
