Determine the pH of a solution of 10-3 M sodium formate. (Formate is a byproduct of microbial metabolism, and can also serve as an energy source for anaerobic bacteria. It is produced natrually from degradation of organic matter, and also anthropogenically from fuel combustion.) The acid dissociation constant, Ka for formic acid is 10-3.7. Assume T=4*C and I=0.
