∙ 11y agoThe logarithm of a number less than 1 is negative. Therefore, -log 0.5 is the negative logarithm of 0.5 which is equal to -0.301.
pH = - log[H3O+]
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
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.
To calculate the hydroxide ion concentration in the solution, first calculate the ammonia concentration based on the NH3 concentration (NH3 is a weak base that accepts a proton to form NH4 + OH-). Then, use the Kb value for NH3 to find the OH- concentration from NH3's hydrolysis reaction. Finally, don't forget to consider the contribution of OH- from the dissociation of NH4OH for the total OH- concentration.
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.
You calculate a log, you do not solve a log!
You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.

pH = - log[H3O+]
Use the LOG function. =LOG(n,b) n = Number b = Base =LOG(2,10) = 0.30103
g=(log Nt- log Nto)/log 2 where N=absorbance reading @ time indicated MGT= (t-to)/g
You can calculate that on any scientific calculator - like the calculator on Windows (if you change the options, to display as a scientific calculator). Log base 4 of 27 is the same as log 27 / log 4. You can use logarithms in any base to calculate that - just use the same base for both logarithms.
you see, i don't know.
The pH is the negative log of [H+].
It is: 10 0.2084413564 = 1.616 by using a scientific calculator
