Homework Help: Chemistry

Posted by Sandy on Saturday, March 29, 2014 at 12:36pm.

In this experiment NaOH is standardized to titrate it with vinegar so thtat the percent by mass of the acetic acid can be determined.

How does dissolved CO2 in distilled water affect the accuracy of the determination of a NaOH solution's concentration? How is the term acid anhydride applied here?

Is the answer that the added CO2 reacts with NaOH to form Na2CO3 when titrated and the NaOH and the Na2CO3 is also titrated, so there is no difference?

Or is there a difference? high determination of a NaOH solution's concentration? low? How does the CO2 affect the determination of a NaOH solution's concentration?
