It's highly flammable. It's a potent carcinogen (causes cancer). It's corrosive. It's basic. It's an oxidant. It's a teratogen (causes birth defects). (b) Which of the following are hazardous properties of sodium thiocyanate? It's a teratogen (causes birth defects). It's highly flammable. It's an irritant. It's acidic. It's basic. It's a potent carcinogen (causes cancer). It's toxic. (c) If any of the solutions in this experiment are spilled on skin or clothing, what is the first thing to do? Flush the area with water. Clean up any spills on the floor or at your lab bench. Go to the TA and tell him/her about the spill. Neutralize the chemical with sodium thiosulfate solution.

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
