pH is a logarithm, not a normal scale
Understand why one pH unit means a tenfold change in hydrogen ion concentration.
Published:
pH numbers look small, but the scale is compressed. A one-unit change is chemically large.
The main idea
Remember that lower pH means higher , and each step changes concentration by a factor of .
A short example
A solution at pH has ten times more hydrogen ion concentration than a solution at pH .
Check while you solve
- Lower pH means more acidic.
- One pH unit is a factor of ten.
- Use brackets for concentration.
