In reaction 1, concentrated sulfuric acid is added to potassium chloride, and the gas given off is passed through aqueous potassium iodide solution. In reaction 2, potassium chloride is dissolved in aqueous ammonia and the resulting solution is then mixed with aqueous silver nitrate. What are the observations for reactions 1 and 2?
- Abrown solution; colourless solution
- Bbrown solution; white precipitate
- Ccolourless solution; colourless solution
- Dcolourless solution; white precipitate
