Hello, So as the end of the year comes to an end, AP Chemistry is getting increasingly more difficult to the point where I don't understand anymore. In our homework there is a questions asking to calculate the pH of a buffered solution. The only information it gives you is the chemical formula and the molarity. i.e Calculate the pH of each of the following buffered solutions: a. 0.50 M C2H5NH2/0.25 M C2H5NH3Cl I'm not quite sure how I'm suppose to be able to figure out the pH without having a Ka/Kb value given? Is the question assuming that I need to know what the Ka/Kb value? Or am I missing something entirely? Thanks for the help!
