For which pH change is there the maximum increase in acidity? | | Initial pH | Final pH | ---------|------------|---------- 1\. | 1 | 3 | 2\. | 2 | 6 | 3\. | 3 | 1 | 4\. | 6 | 2 |

4. 6 2 Reason According to the pH scale, lesser the pH more is the acidity. When pH decreases from 6 to 2, the amount of H+ increases 10,000 times. pH= −log10 [H+ ] [H+ ] = 10-pH ​ Initial [H+] = 10-6 = 0.000001 mol/L Final [H+] = 10-2 = 0.01 mol/L Change: = 10,000 times more acidic
