He has contributed to newspapers and online magazines, including "The Evening Telegram" and cbc. A practical approach to the course delivery is emphasised through the interdisciplinary group 4 project and a mixture of both short-term and long-term experiments and investigations.
As a result, it is a buffer solution. Students have opportunities to design investigations, collect data, develop manipulative skills, analyse results, collaborate with peers and evaluate and communicate their findings. As expected, the solubility will be directly proportional to the temperature, for as the temperature increases so will the molar concentration of KCl in distilled water.
If the experimenter were to weigh the mass of one beaker and take it as a default mass, the latter may be a source of error.
While there are core skills and activities common to both SL and HL, students at HL are required to study some topics in greater depth, to study additional topics and to study extension material of a more demanding nature in the options.
One lab experiment that you can do with organic materials is to separate the constituent compounds of a larger organic compound. This takes place because the strong base neutralises some of the acid molecules forming its conjugate base of the weak acid. Push the contents of each syringe containing samples from the solutions in beakers 1, 2, 3, 4, 5 and 6 into the 50ml beakers labeled 1, 2, 3, 4, 5 and 6 respectively.
Heat each of the 50 ml beakers until complete evaporation of the water occurs, and then immediately place each beaker on the balance and record the mass. Topics like reaction speeds, energy transfer rates and electricity are part of kinetics.

Variables Dependant variable The dependant variable will be the solubility of Potassium chloride in water that will be calculated at different temperatures. The weight of each 50ml beaker used for weighing the mass of dissolved Potassium chloride after the evaporation of water should be recorded. If the solutions were not supersaturated, an increase in solubility will not be detectable. We have used accurate equipment to measure the pH and volume thus errors are within an acceptable range. Kinetics Kinetics is the study of movement and energy. Heat each of the 50 ml beakers until complete evaporation of the water occurs, and then immediately place each beaker on the balance and record the mass. Controlled variables The volume of distilled water used to dissolve Potassium chloride in each beaker The amount of Potassium chloride deposited into each beaker. However, we should not forget the limitations and errors that are not taken in account in the raw results. The graph also illustrates several typical features of weak acid titrations.However, we should not forget the limitations and errors that are not taken in account in the raw results.
