Let's explain part (d). Part (d): Explain why in a strong acid solution, the hydronium ion concentration doubles as the total acid concentration doubles, whereas in a weak acid solution, it increases only slightly to about a factor 1.4. Strong Acid: Strong acids dissociate completely (HA H^+ + A^-). Thus, the hydronium ion concentration, [H_3O^+], is directly proportional to the initial acid concentration. Doubling the initial acid concentration therefore doubles [H_3O^+]. Weak Acid: Weak acids only partially dissociate, establishing an equilibrium (HA H^+ + A^-). The equilibrium expression is K_a = ([H_3O^+]^2)/([HA]_0) (assuming [H_3O^+] [HA]_0). This implies [H_3O^+] sqrt([HA]_0). Therefore, doubling the initial weak acid concentration increases [H_3O^+] by a factor of sqrt(2) ≈ 1.4. Two more parts to go! Send me the next one 📸
