Answer:
<em>The solution with the lowest pH is 0.1 M HCl.</em>
Explanation:
Since the three solutions have the same concentration (0,1M) it is only necessary to look at the pKa of each solution.
Also, knowing that a higher pKa means a lower Ka, because pKa = -Log (Ka). Thus, a lower Ka means a lower concentration of protons with a higher pH ( pH = -Log [H+].
The HCl doesn't have a pKa because is a strong acid that dissociates completely. Therefore, this solution produces a lower pH. Looking at the pKa of acetic acid and formic acid solutions, the second with the lowest pH is the formic acid solutions and the higher pH is for the acetic acid solution.
