It is the negative value of the 10-base logarithmof [positive real number]
(cf. mathematics)
The formula to calculate pH slope is ΔpH/Δlog[H+], where ΔpH is the change in pH and Δlog[H+] is the change in the log concentration of hydrogen ions. This formula is used to determine the sensitivity of a pH electrode.
pH+pOH=14 -> pH+5.010=14 -> pH= 8.99
The pH of a solution can be calculated using the formula pH = -log[H3O+]. Plugging in the concentration of H3O+ given (2.4 x 10^-10 M), we get pH = -log(2.4 x 10^-10) = 9.62. Therefore, the pH of this solution is 9.62.
pH = -log(H+ concentration in moles/liter), so if that is the unit you have it in, then -log(2.3 x 10-4) = 3.64
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
pH = pKa + log([A-]/[HA])
pH is the negative log of the hydronium ion concentration. It seems a little grandiose to call this a "formula", but here you go: pH = -log[H3O+]
The formula to calculate pH slope is ΔpH/Δlog[H+], where ΔpH is the change in pH and Δlog[H+] is the change in the log concentration of hydrogen ions. This formula is used to determine the sensitivity of a pH electrode.
The pH of a solution can be calculated using the formula pH = -log[H+]. Substituting the given H+ concentration (3.7x10-6) into the formula gives pH = -log(3.7x10-6) ≈ 5.43. Therefore, the pH of the solution is approximately 5.43.
-log [h30+]
pH=-log(H+)
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
Let ROH represent the alcoholROH <==> RO^- + H+ Ka = [H+][RO-]/[ROH] Solve for [H+] and take the negative log to get the pH
pH = -log[H+] where H+ equals the concentration of hydrogen ions in a given solution.
pH = -log[H3O+] = -log(2.6*10-9) = -(-8.58) = 8.6
The pH of the solution can be calculated using the formula: pH = -log[H3O+]. Substituting the given value of [H3O+] = 2 x 10^-4M into the formula, pH = -log(2 x 10^-4) = 3.7. Therefore, the pH of the solution is 3.7.
The pH of a solution can be calculated using the formula pH = -log[H+]. Given that the hydronium ion concentration is 10^-1 M, the pH of the solution is pH = -log(10^-1) = 1. So, the pH of the solution is 1.
