WebAt pH 7, the substance or solution is at neutral and means that the concentration of H + and OH - ion is the same. From the range 1-7, a solution is acidic. So, whenever the value of a pH is less than 7, it is considered acidic. There are more H + than OH - in an acidic solution. Note The pH scale does not have an upper nor lower bound.
