A solution is prepared at 25°C that is initially 0.43M in acetic acid HCH3CO2 , a weak acid with =Ka×1.810−5 , and 0.10M in sodium acetate NaCH3CO2 . Calculate the pH of the solution. Round to 2 decimal places.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
