摘要
Measurements of pH usually lie in the range of 0 to 14, and this scale normally covers variability in the laboratory and the natural world, where neutral pH is considered to fall in the middle of this scale. Solutions with negative pH are possible theoretically but beyond the range of most sensors and buffers.
