Why 7 is a neutral point in pH?

Well the way pH works is it's based on the difference between H+ and OH- ions. Take water for example. Water is 7, it's neutral. Water is H2O. H+ and OH- combined equals H2O, and the + and - cancel each other out. I can explain it further if you don't quite understand.

pH Indicator Solution, Most of the water solution including chemical test, titration, and preparation. For that mixture include pH Indicator Solution and standard solutions, which are all important in laboratory analysis. A ph indicator is a halochromic chemical compound that is added in the small amount to a solution so that the ph of the solution can be determined visually
