Lesson details
Key learning points
- Choosing the correct equipment is crucial for obtaining accurate and reliable results.
- An upturned measuring cylinder is suitable for reactions producing large volumes of gas at moderate rates.
- Gas syringes are ideal for measuring small volumes of gas with high precision.
- The size of the measuring equipment should be close to the expected volume of gas produced.
- Light sensors can be used to measure the percentage of light transmitted through a reaction producing a precipitate.
Common misconception
Thinking that precise and accurate are the same thing.
It may help to draw a bullseye target board. Precise results will all be close to each other but may not be near the bullseye. Accurate results will be near the bullseye but may be more scattered if they are not precise.
Keywords
Rate of reaction - Rate of reaction is the speed with which a chemical reaction takes place, measured by the amount of a reactant used or amount of product formed in a given time.
Volume - Volume is how much 3D space matter occupies. It is usually measured in cm³.
Accurate - Accurate measurements are those that are close to the true value.
Precise - Precise measurements have very little spread from the mean value. They are values that lie close to each other.
