Detailed explanation-1: -A solution with a pH of 7 is neutral. A solution with a pH of less than 7 is acidic. A solution with a pH greater than 7 is basic. The pH of the solution is equal to 7 suggests that the solution is neutral that means the amount of acid is equal to the amount of base.
Detailed explanation-2: -The pH scale is centered on 7-meaning that a solution with a pH of 7 is perfectly neutral (neither acidic nor basic).
Detailed explanation-3: -It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. All other substances are compared to this neutral point.
