Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
