Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
<span>The pH is given by the Henderson - Hasselbalch equation:
pH = pKa + log([A-]/[HA]) pH = -log(</span><span>1.3 x 10^-5) + log(0.50/0.40) pH = 4.98 The answer to this question is 4.98. </span>
