How many grams of dipotassium succinate trihydrate (K2C4H4O4·3H2O, MW = 248.32 g/mol) must be added to 790.0 mL of a 0.0522 M succinic acid solution to produce a pH of 5.872? Succinic acid has pKa values of 4.207 (pKa1) and 5.636 (pKa2).
is the pH of the current solution before the addition of the buffer 1/2(pka1+pka2)? otherwise, what is the first step to be taken in this problem?
