Acid and Base Concentrations
What is another name for base?
Alkaline
Each whole number on the pH scale represents
a tenfold difference in hydrogen ion concentration.
Solutions with more hydrogen ions than hydroxide ions are
acidic.
Solutions with more hydroxide ions than hydrogen ions are
basic or alkaline.
Buffers are
chemicals that resist pH change.
As the hydrogen ion concentration increases, the pH
decreases.
Hydrogen ion concentration is typically measured in
grams of ions per liter of solution.
Acidic solutions have pH values that are
less than 7.0.
Alkaline solutions have pH values that are
more than 7.0.
Solutions with equal number of hydrogen ions and hydroxide ions are
neutral.
The pH scale ranges from
0 to 14.
A solution with a hydrogen ion concentration of 0.1 grams per liter has a pH value of
1.0.
A solution with a hydrogen ion concentration of 0.001 grams per liter has a pH value of
3.0.
A neutral pH is
7.0.
The normal pH of blood is
7.35 - 7.45.
Acidosis is
a fall in blood pH.
Alkalosis is
a rise in blood pH.
The pH scale is
a shorthand system used to indicate the concentration of hydrogen ions.
