Practical 6.1B Precipitation Reactions
Practical 6.1B Precipitation Reactions
Draw a grid for the solutions you are given: each solution across the top, each solution down the side. Put a cross in the boxes where you would be midxing two things the same.
Place a small quantity of solution 1 (top left of table) into each of the wells for the number of solutions you have available to add.
Add the other solutions to each well. Record into your grid whether soluble or if a precipitate forms.
Carefully add the chemicals to the waste beaker. Rinse the well very thoroughly.
Repeat for the remaining solutions.

IQ3. How fast are chemical reactions?
3.1 Define reaction rate as change in concentration with time.
3.2 Use collision theory to explain how and why reaction rate is affected by temperature, surface area, concentration and the presence of a catalyst.
3.3 Design, conduct and analyse valid, reliable and accurate scientific investigations of the factors that affect reaction rate.
