pH = -log [H3O+]
[H3O+] = 10^(-pH)

[H3O+] = 10^(-9.8)

[H3O+] = 1.66x10^(-10)


Therefore the concentration of H3O+ in a solution with a pH of 9.8 is 1.66x10^(-10)

By definition, "pH" is the negative of the logarithm to the base 10 of the hydrogen ion concentration in moles per liter. Therefore, the answer to the question is the antilogarithm of -9.75. To find a numerical value, rewrite the number -9.75 as 0.25 - 10. The antilogarithm of 0.25 is about 1.78; therefore, the hydrogen ion concentration is about 1.78 X 10^(-10), to the justified number of significant digits.

What is the pH of a cleaning solution with a H3O 7.4 10-9 M H3O?

By definition: pH = -log[H3O+]So pH = -log(7.4*10-9) = 8.13


What is the pH of a solution with a H3O of 7.9x10-11 M?

pH = -log[H3O+] = -log(7.9*10^-11) = 10.1


What is pH of a substance?

The pH of a substance tells if it's an acid, neutral, or a base. With all deference to the asker and to the previous answerer, technically substances don't have pH's. Aqueous solutions have pH's, and the pH tells you (on a logarithmic scale) the concentration of H+ (or more precisely H3O+) in that solution. A substance is an acid if it lowers the pH of a solution when it is dissolved. It does this by donating protons (H+'s) to water molecules to create more H3O+. A substance is a base if it increases the pH of a solution by accepting a proton from water molecules to form OH-. H3O+ and OH- are in equilibrium with each other in solution, so the more OH- you create, the less H3O+ will be in solution and the higher the pH. So a better answer to the question is that "The pH of a solution tells you if its an acidic, neutral, or basic solution."


What is the pH of a solution with 0001 M H3O?

3. since the [H+]=0.001 M then pH= -log[H+] -log(0.001)=3 pH=3.


What is the H3O concentration in a solution with a pH of 2.34?

pH = (by definition) = -log10[H3O+] , no matter what kind of acid,This inverted to:[H3O+] = 10-pH = becomes 10-2.9 = 1.3*10-3 mol/lNote: [H3O+] = concentration of hydronium ions (mol/l),which is the same as (or equivalent with) saying H+ ions concentration in water

What formula can you use to calculate the H3O plus?

In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).

What is the H3O plus concentration in a solution that is 100 times less acidic than one having a pH of 3.22?

The H3O+ concentration in a solution with pH 3.22 = 1x10^-3.22 M or 6.03x10^-4 M.If a solution is 100 times less acidic, then the H3O+ concentration will be 6.03x10^-6 M.Put another way, 100 times less acidic will have a pH of 5.22 and H3O+ = 1x10^-5.22 = 6.03x10^-6M


What does pH measure How is pH defined?

The pH is a measure of how acidic or basic(alkaline) an aqueous solution is.Pure water is neutral, with a pH = 7. Things with a pH 7 are basic.The theoretical pH of an aqueous solution is defined this way:pH = -log10 [H3O]Related Information:The pH approximates the negative logarithm, base 10, of the Hydronium ion (H3O+) molar concentration of an aqueous solution. It's an indicator of the relative acidity or basicity (alkalinity) of the solution.What makes a solution acidic is the amount of H3O+ in it. A highly acidic solution will have a high concentration of H3O+, and so it will have a low pH. A basic solution has a very low concentration of H3O+, and so it has a high pH. Note that H3O+ and H+ really refer to the same thing, but H+ doesn't actually exist by itself in water: it immediately combines with an H2O molecule to form H3O+ instead.Substances with very high, or very low, pH are dangerous to human hair, eyes, and skin.Examples: pH of common substances are:Stomach acid -- 1Lemon juice -- 2.2Pure water -- 7Milk of magnesia -- 10.5


What is the pH of a solution with H3O plus equals 1 x 10-9M?

pH = -log(hydronium concentration) [Hydronium is H3O.-log(1 x 10-9) = 9


How many more H plus ions does a solution with a pH of 4 than a solution with a pH of 5?

It has 10 times as many. pH is roughly the same as "log [H3O+]". This means "10 to what power is equal to the concentration of H3O+ ions?" So, if you go from pH 5 to pH 4, you've got a concentration of ten times fewer H3O+ ions, and ten times more H+ ions.
