Chem ILP~

Yo guyz~

For those who don't have the chem ilp guidelines, below is the guidelines..

Independent learning – Stoichiometry 2006

Guideline:
1. General Strategy
2. Justification
3. Procedures – numbered steps
4. Calculations
5. Safety
6. Reliability

General Strategy
- provides theoretical background using scientific knowledge and understanding e.g. explain clearly the need to first add excess standard acid followed by a back titration between NaOH and a diluted excess acid solution

Justification
- provide a correct calculation to ascertain amount to be used and explain why dilution is necessary and use it to explain the basis for the design

Detailed procedure
- numbered steps including type and capacity of apparatus, chemicals and their concentrations where appropriate, and details of experimental techniques

Calculations
- using hypothetical algebraic values, show how to use the results to calculate the amount of NaHCO3 in the sample and hence the percentage of NaCl in the sample, stating any assumptions used

Safety
- at least 2 significant safety precautions, with reasons

Reliability
- at least 2 points to ensure reliability of results, with reasons

Hope this will help you in your chem ilp.. =p
