What is the measure of the concentration of hydronium ions in a solution?

The measure of the concentration of hydronium ions in a solution is the pH.


How do hydroxyl ions and hydronium ions affect 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


How would you Calculate the H3O ion concentration in a solution with pH3 and a solution with pH8?

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.


What happens to the concentration of hydronium ions as the pH of a solution increases?

hydronium ion concentration decreases


Is pH an atom?

No. pH is the measure of the concentration of hydrogen ions (technically hydronium ions) in a solution of water.


What factor does the pH scale measure?

The concentration of hydronium ions in a solution with pH of 4 is how many times that of a solution with a pH of 2?

100


Is 9 the pH of equal numbers of hydronium ions and hydroxide ions?

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.


How is pH related to the concentration of hydronium ions in solution?

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.


What is the name of the number scale chemists use to describe the concentration of hydronium ions in a solution?

The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale


How would an increase in the concentration of hydronium ions in solution affect the pH?

H3O+The increased concentration of this ion in a solution would lower the pH


Is pH affected by concentration?

pH is a measure of the concentration of free protons in a solution (or in the case of aqueous solutions, hydronium ions).


An increase in the concentration hydronium ions in a solution may do what to the PH?

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.


What is the pH value of an acid solution?

pH = - log [h3o+] The pH is equal to the negative log of the concentration of hydronium ions. The concentration of h+ is equivalent.


What is the measurement system called that indicate the concentration of H ions in solution?

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?

What is the hydronium ion concentration of an aqueous solution with a pH = 2.00?


What is measured on a pH scale?

The inverse logarithm of the concentration of hydronium ions in a water solution; basicaly, how acidic a solution is.


What makes a solution acidic basic or neutral?

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.


What is the relationship between the pH of a solution and the concentration of hydrogen ions in the solution?

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).


What the pH number of an indicator for the concentration of?

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.


What does it mean when the pH in a solution is low?

A low solution pH means a high concentration of hydronium (H+) ions; i.e. acidic conditions.


What is the pH level of hydronium?

pH is defined by the concentration of Hydronium ions. There is no definite pH for the hydronium ion or any acid or base.


How is the concentration of hydronium ions and hydroxide ions related to pH?

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.


What happens to concentration of the hydronium ions as the pH decreases?

The concentration increases as the pH decreases.


How much pH is in strong acid?

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.
