The lower the pH reading, the more acidic the solution. Readings from 0â7 are considered acidic, and numbers from 7.0â14 are considered basic, or alkaline. Pure water, in the very middle of the (logarithmic) pH scale, has a pH of 7.0, which is considered neutral.

Last 10 results of this IQ Test : The bell curve (also called a normal curve or normal distribution) is a graph that shows approximately how much of the population falls into each IQ range. In theory, if we tested everyone in the world with a traditional IQ test, most people would score in the  Average range.
