Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides o
f a center magnet that cannot move. She moves both vehicles one space closer to the center magnet.
How did the potential energy of the two vehicles change? Did the potential energy of one vehicle change more than the other? Why do you think so?

The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high will have:
Option B. A low and a high
This characteristic can be explained as:
- The concentrations of
and
are inversely dependent on each other so when the concentration of raises then the concentration of
- The pH of a solution or substance is calculated with the help of:
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.
