Before answering this question, here is a short text about pH!
pH or potential of hydrogen is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH (less than 7). More alkaline solutions have higher pH (greater than 7). Substances which are not acidic or alkaline (neutral) usually have a pH of 7 (this is the answer to your question).
pH is a measure of the concentration of protons (H+) in a solution. Sørensen introduced this concept in 1909. The "p" stands for the German potenz, meaning power or concentration, and the "H" for the hydrogen ion (H+).
