How are predictions tested in the precipitation reaction lab?
Record your predictions. You will then test your predictions by combining pairs of solutions to see if a precipitate forms. Additionally you may be asked to prepare the standard 0.10M solutions used for this lab. Your teacher may have you do this in advance of the precipitation tests.
When does no precipitate occur in a precipitation reaction?
If no insoluble combination between anions and cations exist, no precipitate will form. Instead, all ions remain in solution and no reaction occurs. In this lab you will use your knowledge of precipitation tables to predict precipitation reactions.
How to do a precipitation reaction in Excel?
On the blank Test Grid provided, list along the top row the Set A solutions you will be testing by giving the formula and charge of the ions present in the solution. An example is shown on the grid. Similarly, list the Set B solutions in the first column. Prepare a second, identical test grid which you will use to record your results.
How are solubility rules used in a precipitation reaction?
In chemistry, this is referred to as a ‘precipitate’, and the whole phenomenon as such is called a ‘precipitation reaction’. As a result of all experiments, it would be able to infer how the solubility rules could be used to explain the products of each precipitation reaction.
