For which acid is the value of the acid-dissociation constant, Ka , the smallest?

Concentration (M) pH of Acid 1 pH of Acid 2 pH of Acid 3 pH of Acid 4
0.010 3.44 2.00 2.92 3.86
0.050 3.09 1.30 2.58 3.51
0.10 2.94 1.00 2.42 3.11
0.50 2.69 (after this is 2.44) 0.30 (after this 0.00) 2.08 (after this is 1.92) 2.96 (after this is 2.73)
1.00

I though it was pH of Acid 2 since the values are small and they are decreasing

The values for pH for all of the acids decrease as you increase the concentration from 0.010 to 1.00 M. The fact that acid 2 has "small" or low values of pH indicates that the Ka is a larger value, i.e that the acid dissociates more than the others.
