When diluting the commercial vinegar, what would have been the effect on acetic acid molairty of failing to rinse the pooped with commercial vinegar, assuming there was some distilled water left in the piper from a previous student? ( think about how the concentration of the commercial vinegar is affected by the water in the piper).
My thought is that the water wouldn't really have an affect on it.
With the misspelling and the wording, I have no idea what you have asked.
To determine the effect of failing to rinse the pipette with commercial vinegar when diluting it, you need to understand how the concentration of acetic acid, the main component of vinegar, is affected by the water in the pipette.
When diluting a solution, the concentration of the solute (in this case, acetic acid) decreases while the volume increases. If there is any leftover distilled water from a previous student in the pipette, it will mix with the commercial vinegar during the dilution process.
In general, commercial vinegar has a specific concentration of acetic acid, typically expressed as a molarity (moles of acetic acid per liter of solution). If you fail to rinse the pipette, the leftover water will effectively increase the volume of the combined solution. As a result, the molarity of acetic acid in the combined solution will be lower than the original concentration of the commercial vinegar.
To prevent the dilution of the acetic acid concentration, it is important to rinse the pipette with the commercial vinegar before using it. This ensures that only the desired amount of commercial vinegar is used for further dilutions, without any dilution from residual water.
In conclusion, failing to rinse the pipette with commercial vinegar could lead to a decrease in the molarity of acetic acid in the solution, resulting in a less concentrated vinegar solution.
