3.4 and 3.5 Concentration of hydrogen ions Flashcards
(3 cards)
1
Q
Concentration of hydrogen ions
A
When an acid is in solution, a higher concentration of H+ ions means that the solution is more acidic, meaning it would have a lower pH
2
Q
Concentration of hydroxide ions
A
When an alkali is in a solution, a higher concentration of OH- ions means that the solution is more alkaline, thus having a higher pH
3
Q
Concentration and pH decreasing
A
As pH decreases by one unit, the H+ concentration of the solution increases by 10.
