pH Values of Common Substances
pH Values of Frequent Substances

In science, pH is a scale (from 0-14) used to measure the acidity or basicity of an answer. An acidic resolution have decrease pH values (lower than 7) whereas a primary resolution has larger pH values (larger than 7). At room temperature, pure water has pH worth of seven, which suggests it’s neither acidic  nor primary in nature. It’s impartial.
