What is the formula of H3O?

H₃O⁺
Hydronium/Formula

How do you find the pOH of NaOH?

Calculate the pH of a 0.1 M NaOH solution. Alternatively we can calculate pOH = – log [OH-]= – log [10-1] = 1 and remembering that pH + pOH = 14 we get pH = 14 – 1 = 13.

How do you find H3O+?

The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or “inverse” log ( – 8.34).

How do you find the H3O of a solution?

How do you find the pOH of a solution?

To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

What is [OH-] = [NaOH]?

First, you need to know that NaOH is a strong base, this means that the dissociation of NaOH into its ions is 100\%. NaOH (s) –> Na+ (aq) + OH- (aq) is 100\% forward reaction, therefore [OH-] = [NaOH] = 0.65 M Know, you can determine pH and [H3O+] in two different ways, pick your favourite!

What is the concentration of H2SO4 in a solution of NaOH?

Since the initial mole of H2SO4 being 2 mmoles, and of this amount is consumed by NaOH as much as 0.075 mmole, thus the amount of H2SO4 left over = 2 mmoles – 0.075 mmole = 1.925 mmoles. Thus, the concentration of H2SO4 in the solution is 1.925 mmoles/26 mL.

What is the pH of 10 ^ (-14) concentrated H+?

H+ + OH- —> H2O. Thus, the concentration will go even lower than 10 ^ (-14). And the pH of 10 ^ (-14) concentrated H+ is 14. If you go even less concentrated, like this case, the pH will rise further. And that’s all. By the way, the strongest carborane superacid has the chemical structure H (CHB11C11).

What is the value of [H3O+] = kW/ [Oh-]?

Kw = [H3O+] [OH-] = 1.0×10^-14 Therefore, [H3O+] = Kw/ [OH-] = 1×10^-14 / 0.65 = 1.5×10^-14 M If you keep your unrounded digits throughout your calculations, then round off at the end, both methods will yield the same answers, Webmaster?
