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.
Bell curve may refer to: 1  A Gaussian function, a specific kind of function whose graph is a bell-shaped curve. 2  Normal (Gaussian) distribution, whose density function is a Gaussian function.ell curve may refer to: 1  A Gaussian function, a specific kind of function whose graph is a bell-shaped curve. 2  Normal (Gaussian) distribution, whose density function is a Gaussian function.
This is not a lesson in the statistical formulation of the bell curve; rather, it is a lesson to help you fully understand the impact on grades that the bell curve produces. First, to help you better understand the basics behind the bell curve concept, let's start by explaining what the bell curve is.n a bell curve like this, the top of the curve demonstrates the C's, the far right side of the curve is where the B's and A's are placed, and the far left side of the curve is where the D's and F's are placed.
