Ideas for Individual Investigation topics

• Transition metal complex ions (efects o metals, ligands,

oxidation states on the colour o the ion)• Natural indicators (sources, stability, Ka values, end point range)• Extraction o oil rom spices (using diferent sources o spices,

diferent storage conditions)• Efectiveness o diferent water puri cation methods on dissolved

ions!• Efectiveness o diferent salts or road snow removal ( ree"ing

point depression, efect on diferent materials)• #n$depth %inetics investigation into a speci c reaction (involving

the determination o the order and rate constant)• &elting points o group ' metals and the diferent types o

crystal lattice• Thermodynamic data or ionic compounds! The enthalpy o

solution can be ound out in the lab! Ksp can be calculated bygravimetric determination! The energy value can be calculatedusing K TlnK and then the change in entropy value!

• The amount o nitrogen in ertili"ers (reacting with excess Na*+and titrating with standard + l solution)

• -itamin content in vegetables• +and $ ub .aniti"ers/ Kinetic study using evaporation o

diferent types o saniti"ers• #odine numbers o palm oil as compared to other coo%ing oils

(such as coconut oil, corn oil, sun0ower oil) and compare them tosecondary sources

• 1n expansion o the determination o manganese in a paper clip(one o the possible labs mentioned in 1!' &etals and inductivelycoupled plasma (# 2) spectroscopy)
