Chemistry Internal Assessment
Introduction:
The experiment is to conclude which aqueous solution of the chlorides has the highest boiling point out of the five that has been tested.there will be five different chloride compounds mixed into water and be heated till it is boiling. The interest for this topic comes from how intermolecular forces affect the molecules by either repulsing and attracting molecules due to polarity. This idea interests me because when cooking and boiling salt water, it takes longer and for it to boil as well as mixing anything else into the water.
Research Question: How does different chlorides affect the boiling point of water?
Background research:
When a solute is added to water the boiling point of the water gets higher. This is the boiling point elevation. The cause of this is vapor pressure. The vapor pressure of the solvent is less than the vapor pressure of the pure solvent (water). The boiling point of the solution would need to be heated to a higher temperature to be equivalent to the external pressure. Different solutions will have different vapor pressure. When adding a solution to water the boiling point is elevated and the temperature would need to be raised to boil the solution.
Methodology: For this experiment the independent variable would be the solute that is being …show more content…
The beaker has a percent error of plus or minus 5%. The balance being used also only measure to the hundredths place which is crucial since the experiment is to gather data depending on how much solvent is being used. The temperature probe also leaves room for error. It only measures to the tenths place and there is human error since we can accidentally touch the bottom of the beaker which could change the temperature of the probe entirely. The probe isn’t entirely accurate since it would range and the error percent on the computer tells me how much of an error could be in the
