The name given to a chemical system that prevent changes in hydrogen ion concentration?
A buffer
How does pH relate to hydrogen ion concentration?
pH is a measure of the concentration of hydrogen ions in a solution. As pH decreases, the hydrogen ion concentration increases, and as pH increases, the hydrogen ion concentration decreases. pH is calculated using the negative logarithm of the hydrogen ion concentration.
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
What would be the pH of a solution with a hydrogen ion concentration of 0.00001m?
The pH of a solution can be calculated using the formula pH = -log[H+]. Given a hydrogen ion concentration of 0.00001 M, the pH would be 5.
What is the pH of a solution that has a hydrogen ion concentration of 110?
A hydrogen ion concentration of 110? 110 what? Or is that supposed to be 1x101
What is the hydrogen-ion concentration if the acid dissociation constant is 0.000 001 and the acid concentration is 0.01 M?
The concentration in such case is calculated including the H ion concentration contributede by water, So the [H] is .00000001+.0000001
What is the measurement of hydrogen ion concentration?
A measurement of hydrogen ion concentration is pH, which equals-log[H+], which is the negative logarithm of the hydrogen ion concentration (actually activity, but that is usually ignored). This quantity can be measured with a hydrogen electrode (as found in a pH meter), which is a type of ion selective electrode.
What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
What effect does dilution have on the hydrogen ion concentration of sulphuric acid?
Diluting sulfuric acid decreases the hydrogen ion concentration because the concentration of sulfuric acid molecules in the solution decreases. As a result, the overall hydrogen ion concentration decreases in the diluted solution.
What information is necessary to determine the pH of a solution when you given hydroxide ion concentration?
To determine the pH of a solution from the hydroxide ion concentration, you also need the concentration of the hydrogen ion. Once you have that information, you can use the equation pH = 14 - pOH, where pOH is calculated as -log[OH-] and [OH-] is the hydroxide ion concentration.
Which kind of compound increases the hydrogen ion concentration in a solution?
Acids increase the hydrogen ion concentration in a solution.
How does the concentration of hydrogen ions vary with pH?
pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.
