Lower pHs are more acidic Higher pHs are more basic. Therefore, the pH of 5 will be more acidic than pH of 7 ** also, the pH of 7 is neutral. Edit by Kelvin876: Higher pHs are alkalines. **Each number lower is 10 times greater in acidity than the prior number. This would mean that a solution with a pH of 5 is 100 times greater in acidity compared to a solution with a pH of 7.
Necause the 2 indicators have different PHs level
enzymatic activity is pH specific. Alteration of pH of media causes ionization of amino acids. Acidic amino acids have additional carboxyl functional groups . Basic amino acids have additional amino functional groups As a result of ionization, 3-D structure existing on the base of IONIC BONDS is altered. Moreover shape is also effected. catalytic activiyty is effected.
