Key Equations pH = −log[H3O+] pOH = −log[OH−] [H3O+] =10−pH [OH−] =10−pOH pH + pOH = pKw = 14.00 at 25 °CChemistry End of Chapter Exercises Explain why a sample of pure water at 40 °C is neutral even
Now you know how to calculate pH using pH equations. If you find these calculations time-consuming, feel free to use our pH calculator. Select your chemical and its concentration, and watch it do all the work for you. The mind behind the pH calculator Biochemists, environmental scientists,...
This packages computes the pH of a monoprotic acid solution, given its concentration and its dissociation costant. pH computes the exact pH values solving the equations of both the water and the acid equilibria. For didactical purposes an alternative rough method, using the simplified formula pH...
Acid Base Equations pH = -log [H3O+] [H3O+] = 10^(-pH) pOH = -log [OH-] [OH-] = 10^(-pOH) pH + pOH = 14 [H3O+] [OH-] = 1 x 10-14 Sig Figs and pH The number of decimal places in the log value, pH value, is equal to the number of significant figures in the ...

Constitutive equations are developed by means of the free energy imbalance inequality for an arbitrary deformation of a PE gel accompanied by swelling. To reduce the number of adjustable functions and to make the model tractable, these relations are simplified with the help of the principle of ...
pH vs log concentration diagrams « on: May 22, 2007, 06:40:02 AM » HiJust wondering if anybody could explain to me in terms of equations why the [H+] and [OH-] lines in logarithmic diagrams are straight lines with negative and positive slopes respectively.I know why the slopes...
