45. The weak basein) in the following list is (are) (1 804(109) + HO HO (aq) + HSO4 (ac) (11) Vụ Ô (aq) + 0 + HÔ" (Ag) + HOA (ac) (m) CHCOOHH00 HO (0) CH.COO(ac) (IV) NaOH(aq). Ho Na lac) + OH( M CH:Nth (n) H0 CHNEL"0) + OH() (A) Only IV (H) Only v (C) IVAV (D) 1. &V 4. Which of the following in the Archenius Theory of acids and basea? An act dictates in water to form hydrogen ions (H) and a base latin water to produce hydroxide ions (OH). An acidi proton donor and a base is proton acceptor Adicts are substances with a very high pet greater than 10) and bases are substances with a very low prl(less than 3), (D) None of the above

Answer 1

Arrhenius Theory Acid: Substance that in hydrogen ions H. aqueous solution dissociates to produce Examples: HCI — H + cr H,804 - H + HSO4 CH,COOH — H* + CH3COO aqueous solution dissociates to produce Base: Substance that in hydroxide ions HO. Examples: NaOH — Nat + HO- Ca(OH)2 — NH,OH Ca* + 2H0 + NH, + HO So is the option (A)
