One major factor that affected the result of this experiment was to strength of the sodium and sodium hydroxide. Thus, the final answer did not match the theoretical value accurately because the strength was weakened, meaning that the numbers used to calculate the molar concentration were not as accurate.

This value includes the both uncertainties regarding those that applied when the solutions were made eg. Conclusion In conclusion, this experiment found the molar concentration of acetic acid in vinegar to be 0.

In addition, the equipment used could have also contributed to the error as all pieces of apparatus have an uncertainty attached to it.

However, the exact value of the amount of acetic acid present in a mL sample of vinegar is 0. If either of these substances is left open in the atmosphere, they begin to lose their strength.

Analysis The purpose of this investigation was to determine to molar concentration of acetic acid in vinegar.

Human judgment also accounts for some of the error in this experiment as the person performing the experiment was required to read off many measurements from the pipette and burette. These uncertainties can be reduced by using more accurate equipments, for example a more accurate mass balance.

Also, limiting the transfer of solution from one container to another will also reduce the amount of error. Calculations and Data Processing Analysis The purpose of this investigation was to determine to molar concentration of acetic acid in vinegar.

In order to prevent this error from affecting the results of the experiment, one should attempt to keep the sodium and sodium hydroxide in an enclosed environment at all times, thus limiting the time it has to interact with the atmosphere.

This experiment showed that the concentration of acetic acid is 0. These uncertainties are then applied to calculations in order to keep up the amount of uncertainty associated with the amount of material used.

The reactions that occurred in during the experiment were neutralization reactions, meaning that the moles of acid equaled the moles base at the end of the experiment. During the experiment, the sodium and sodium hydroxide were both left open to interact with the environment for some time.

This error can be reduced by always ensuring that readings are always made at eye level and that the same person taking the readings is constant as judgment varies with each person.Nov 25,  · The pharmaceutical quality control laboratory serves one of the most important functions in pharmaceutical production and control.
