acids and bases Flashcards
Define pH
A measure of the hydrogen ion concentration of a solution
Describe the hydrogen/hydroxide concentration of acidic solutions
The concentration of hydrogen ions is greater then the concentration of hydroxide ions
Describe the hydrogen/hydroxide concentration on alkaline solutions
Hydroxide ion concentration is greater then the concentration of hydrogen ions
Describe the hydrogen/hydroxide concentration of neural solutions
Equal concentration of hydrogen and hydroxide ions
When an acidic solution is diluted with water
Concentration of hydrogen ions decreases
Solution becomes less acidic
Ph rises towards 7
When an alkaline solution is diluted with water
The concentration of hydroxide ions decreases
The solution becomes less alkaline
pH decrease towards 7
