Question

Decide whether each chemical reaction in the table below is an oxidation-reduction ("redox") reaction. If the reactic of the reducing agent and the formula of the oxidizing agent. redox reaction? yes no 2 Fe(s) + 3NICI, (aq) — 2FeCl, (aq) + 3Ni (s) reducing agent: oxidizing agent: redox reaction? O yes no 201, (g) + Sn(s) — SnCI, (s) reducing agent: oxidizing agent: 0 redox reaction? yes no HCl(aq) + NH, (aq) → NH,Cl(aq) reducing agent: oxidizing agent:

Answer 1

1. Redox reaction: Yes

Reducing agent: Fe

Oxidizing agent: NiCl₂

2. Redox reaction: Yes

Reducing agent: Sn

Oxidizing agent: Cl₂

3. Redox reaction: No

+2 - 1 Z ir (s) + 3 Nich (as) 2 fell (as) + 3 Ni (s) fe oniclises from o to +2 Conidation) Ni reduces from +2 to o creduction Redox reaction: [Yes Reducing agent [Fe] Onidizing agent: Nich Reducing agent : Species which get oxidized, Onidising agent: Species which get reduced. 20, (99 + $(3) Suchy, ay) . In onidizes from o in Sn to t4 in Sulla Conidation) ₂ reduces from 0 tot in Sulla (reduction) Redox reaction: Yes Reducing agent: [sn] Onidising agent: [ch]

| . SU Hü (aq) + Rits laq? - Rita Cl lago All atoms remain in the same oxidation state. So, there is no oxidation / reduction. Hence, no ca, redox reaction : NO
