Question

Acids and bases: definitions Consider the following reactions: (a) 2 NH3 + Ag* [Ag(NH3)2] (b) NH4 CO32- -NH3 + HCO3 (c) 2 HBr+ Ca(OH)2 CaBr2 + 2 H20 Match with the definitions that apply for the substances indicated. Note: In a given reaction, the same definition must apply for both the acid and base for it to hold true. NH3 in reaction (a) Brønsted-Lowry and Lewis base Agt Brønsted-Lowry and Lewis acid NH4+ Arrhenius, Brønsted-Lowry, and Lewis acid Соз2- Arrhenius, Brønsted-Lowry, and Lewis base HBr Arrhenius, Brønsted-Lowry, and Lewis acid Caа(ОН)2 Arrhenius, Brønsted-Lowry, and Lewis base

Answer 1

(al (b) 10 2NH3 + Ag+ [Ag CNH3l] + NH4 + co²- NH3 + HCO PHBr + CaloH) CaBr + RHO Lewis Base - Those species which to electron deficient species. donates electron pain - Bar Bronsted ion in Lowryn S solution. Those species which donates on Lewis acid » These species accept electron pain from roo nich species in their Vacant orbitar. Arikenius acid Those species which in aqueous solution donates Htion donates or Brionsted Loway acid - Those species which giver Htion in solution. Arrhenius Base - Those species that gives on in aqueous solution & Reaction (asy 3 NH is Lewis base as it is donating electron pair to Agt (electam deficient) _ Ag Agt is Lewis acid as it accepts electron pain from electron rich specie NHST - Arhenius acid because it donates Mt in solution.

co? Arrhenius Base because it is aqueous solution. accepting Ht in HBr → Arhenius acid as it gives it in boat CacOHL Arrhenius Base as it gives D Ht in water
