Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
The pH of a solution with higher hydrogen ion concentration than hydroxide ion concentration will be less than 7, indicating an acidic solution. The exact pH value can be calculated using the formula pH = -log[H+].
Concentration of hydrogen ions in solution is called?
The concentration of hydrogen ions in solution is called pH. It is a measure of the acidity or basicity of a solution on a scale from 0 to 14, with lower values indicating acidity and higher values indicating alkalinity.
Does a pH value signify certain number of hydrogen or hydroxide ions?
"pH" is a convention used as a convenience. It indicates how acidic (or basic, that is, alkaline) a solution is. It is the negative logarithm of the hydrogen ion concentration, usually the latter is expressed in moles (or millimoles) per liter. Moles per liter is, of course, what we call "molarity." pOH is used in the same way, indicating the concentration of hydroxyl ions. Generally, Concentration of hydrogen ions + the concentration of hydroxyl ions = 10-14 A neutral solution has equal numbers of H+ and OH-
PH value of hydrogen peroxide?
scale pH <--- HUH? hehe
Does a pH of 3 have a greater hydrogen ion concentration than a 9 pH?
pH come from "pondus hydrogenii" or "potential hydrogen." It measures the concentration of hydrogen ions. Mathematically, pH = -log[H+] Therefore, to answer your question, a pH of 3 will have a 10-3M of hydrogen ions where as the pH 9 solution will have a 10-9M of hydrogen ions. The lower the pH the higher its H+ concentration and the more acidic it is. (A pH of 9 is actually basic.)
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.
What solution has a greater concentration of hydrogen ions a pH of 7 or a pH of 3?
A solution with a pH of 3 has a greater concentration of hydrogen ions compared to a solution with a pH of 7. The pH scale is logarithmic, so each pH unit represents a tenfold difference in hydrogen ion concentration.
What is the hydrogen-ion concentration for pH 2.7?
The hydrogen-ion concentration for pH 2.7 is 5.01 x 10^-3 moles per liter.
Does a pH of 3 have more hydrogen than a pH of 7?
Yes, a pH of 3 has more hydrogen ions (H+) than a pH of 7. The pH scale is logarithmic, so each unit change represents a tenfold difference in the concentration of hydrogen ions. A decrease in pH corresponds to an increase in hydrogen ion concentration.
What is the change in hydrogen ion concentration when the pH decreases by 3 units?
The change in hydrogen ion concentration is a 1000-fold increase when the pH decreases by 3 units. This is because the pH scale is logarithmic, with each unit change representing a 10-fold change in hydrogen ion concentration.
What is the pH of a solution that has a concentration of hydrochloric acid equal to 0.001 M?
Remembwer pH is = the negative logarithm to base ten, of the hydrogen ion concentration . So with a concentration of 0.001 M The hydrogen ion concentration is 0.001 = 10^(-3) ph = -log(10)[H^+] pH = -log(10)10^-3 pH = -(-3) log(10)10 ( Remember log(10)10 = 1 ) pH = -(-3)(1) = --3 = 3 pH = 3
Why is pH 1 more acidic than pH 3?
pH is a logarithmic scale that measures the concentration of hydrogen ions in a solution. A pH of 1 has a much higher concentration of hydrogen ions compared to a pH of 3, making it more acidic. Each unit change in pH represents a 10-fold difference in hydrogen ion concentration.
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.
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.
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.
What is the pH when hydrogen ion concentration is 7.0 x 10-3 M?
By definition pH = - log10 [H+], where [H+] = concentration H+ of in mol/LSo at [H+] = 7.0*10-3 the answer will be pH = - log (7.0*10-3) = (2.1549) = 2.15
