THE PROPERTIES OF SOLUTIONS. 



[CH. I. 



Series E. Sodium acetate and acetic acid. 



The following series is given as being convenient for certain 

 experiments. It should be noted that the P H of the solutions is 

 only very slightly changed by considerable dilution with water.* 



Preparation of Solutions. 



N. acetic acid is prepared by titration against N. soda. 0-2 N. 

 acetic acid is prepared from this by diluting 200 cc. to 1000 cc. with 

 distilled water. 6-2 N. sodium acetate is prepared by mixing 200 cc. 

 of the N. acetic acid with 200 cc. of the N. soda employed and 

 diluting to 1000 cc. with distilled water. 



Take x cc. of the sodium acetate, and add (IQ-X) cc. of the 

 0-2 N. acetic acid.
