A120 ml portion of 0.4 m acetic acid is being titrated with 0.4 m naoh solution. what is the ph of the solution after 110 ml of the naoh solution has been added? the ionization constant of acetic acid is 1.8 ã 10â5 . 1. ph = 6.84 2. ph = 5.79

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.
