equipment
- lead nitrate
- potassium iodide
- conical flask
- stirring rod
- 250ml beaker
- funnel
- filter paper
method:
1. pour Approximately 10 ml of the potassium iodite solution into the beaker
2. add the same volume of the lead || nitrate.
3.your teacher will show you how to fold the filter paper so it fits inside your funnel.
4. place the funnel, with the filter paper inside it, into the mouth of a conical flask.
5.stir, then carefully pour the precipitate mixture into the funnel.
observations : when i was watching the chemicals go together it turned into a yellow colour. then when we filtered it (got rid of all the liquid) stuck to the filter paper was a yellow pastey resadue . when I felt it (i wasn't suppose to but I did) it felt like cornstarch a bit. the cornstarch resadue was rude
