For reaction 1, concentrated sulfuric acid is mixed with potassium chloride, and the gases formed are passed through aqueous potassium iodide solution. For reaction 2, potassium chloride is first dissolved in aqueous ammonia and the resulting solution is then added to aqueous silver nitrate. What observations would be made in reactions 1 and 2?
- Areaction 1: brown solution; reaction 2: colourless solution
- Breaction 1: brown solution; reaction 2: white precipitate
- Creaction 1: colourless solution; reaction 2: colourless solution
- Dreaction 1: colourless solution; reaction 2: white precipitate
