The pH (pH), pH, or pH (pH) index is the measurement that determines whether the liquid is acidic, alkaline or neutral. Fluids with a pH of less than 7 acids are considered as liquids with a pH greater than 7 alkaline solutions or bases. PH 7 is neutral and is equal to pH of pure water at 25 ° C. The pH of any solution can be determined using a pH indicator.

The pH (sometimes called pH) is the negative of the decimal logarithm of hydrogen ion concentration in a solution and indicates the pH of that solution, which can be measured by the pH index.

Yes. Prof. Barbara is right. Water bodies that have been acidic with less than 7 pH is not potable for drinking (7pH neutralises both the acidic and alkaline measure in water making it pure to consume). Also, acidic water bodies serve as fertile or conducive grounds for bacteria infestation (below 7pH) that negatively affect the purity of the water, poisoning it, making their use by humans and other biological diversities in and around the water bodies hazardous.

yes of cours have effect on bactrio some prefer living in ph up 7 and other prefer down 7

Pretty sure it has !!!! Like everybody I remember 7 is a number !!!

It makes the media more alkaline or acidic so life might or might not thrive

DEFINITELY.

For regular disinfection, solution of much lower or much higher pH are used for that reason.

Does pH of solution has an effect on the bacteria?

Together with other factors like temperature and nutritional requirement, pH also effect the growth of bacteria....where different bacteria have their own favorable pH values....
