ph=-log[H+] so -log [H+]=8 then [H+]=10^(-8) mole/lit
The measure of the concentration of hydronium ions in a solution is the pH.
As the concentration of hydronium ions (H+ ions) increases or as the concentration of hydroxyl ions (OH- ions) decreases, the pH of the solution decreases
In a solution, hydrogen ions normally bond with molecules of water, forming H3O+ (hydronium) ions. Thus, the concentration of the hydronium ions will be the same as the concentration of hydrogen ions, which is related to the pH of a solution according to the following equation: pH = -log[H+] = -log[H3O+] This equation can be solved for the concentration of hydronium ions: [H3O+] = 10-pH Thus, for a solution with a pH of 3, the concentration of hydronium ions will be 10-3 = 0.001 moles/liter, and for a solution with a pH of 8, the concentration of hydronium ions will be 10-8 = 0.00000001 moles/liter.
hydronium ion concentration decreases
No. pH is the measure of the concentration of hydrogen ions (technically hydronium ions) in a solution of water.
The Concentration of hydronium ions in a solution
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
The pH is actually simply the measure of the concentration of these ions. Specifically, it's the presence of these ions in relation to hydroxide.
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
H3O+The increased concentration of this ion in a solution would lower the pH
pH is a measure of the concentration of free protons in a solution (or in the case of aqueous solutions, hydronium ions).
raises the pH Edited by Dr.J.: Are you kidding me? Raising the H3O+ concentration does NOT raise the pH, it LOWERS the pH. I can't believe that 8 people actually found this incorrect answer to be useful.
pH = - log [h3o+] The pH is equal to the negative log of the concentration of hydronium ions. The concentration of h+ is equivalent.
The pH system is used to indicate the concentration of hydronium ('H+') ions in solution. It is governed by the equation pH = -log[H+]
What is the hydronium ion concentration of an aqueous solution with a pH = 2.00?
The inverse logarithm of the concentration of hydronium ions in a water solution; basicaly, how acidic a solution is.
If a solution have a higher concentration of H+ ions, then the solution is an acidic solution. If a solution has a higher concentration of OH- ions, then the solution is a basic solution. The above is an overly simplistic and inaccurate description. Actually it is only the concentration of a type of ion called pi-Hydronium or pH, which have the formula H2OH+. More pi-Hydronium ions (lower pH number) the solution is acidic, same number of pi-Hydronium ions as pure water (pH number exactly 7) the solution is neutral, fewer pi-Hydronium ions (higher pH number) the solution is basic. With solvents other than water, while H+ ions might be able to form, the solution cannot be acidic or basic as pi-Hydronium ions cannot form.
pH is -log10[H3O+]; the negative logarithm (with base 10) of the hydronium concentration (hydrogen ions do not float around on their own. Instead they attach to a water molecule and become a hydronium ion).
The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
A low solution pH means a high concentration of hydronium (H+) ions; i.e. acidic conditions.
pH is defined by the concentration of Hydronium ions. There is no definite pH for the hydronium ion or any acid or base.
The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.
The concentration increases as the pH decreases.
pH is not a measure of how strong an acid is. pH is a measure of the concentration of hydronium ions in a solution, which is dependent on both the strength of the acid or base and its concentration in a given solution.
