The only thing that has been difficult is getting used to my new appetite. I've been throwing out a lot of my food because I physically feel like I cannot eat that much, and if I do eat too much then I don't feel so good.

However, I'm learning to keep all my meals small and frequent (just like I should have been doing all along!). I plan to definitely buy this product again, I really love it and finally, I've successfully changed my eating lifestyle. Dieting is Out.

Mar 05,  · Determination of Ka of Weak Acids. I. II. Date: March 5, Purpose: To measure the pKa value for ionization of two unknown weak acids by using solutions containing equal molar amounts of the weak acids and their conjugate bases which are prepared by “half-neutralization” of the acid. Procedure: Refer to Lab Sheet.5/5(4). The Determination of Ka of Weak Acids Classic Lab Kit for AP* Chemistry allows students to measure the Ka value for the ionization of two unknown acids. pH values are then measured and utilized, calculating the pKa value of each unknown.
