pH = pKa + log([A-]/[HA])
Phenolphthalein is a sensitive pH indicatorwith the formula C20H14O4
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 base chemistry formula for determining the pH of a solution is pH -logH.
pH + pOH =14
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+]
pH=-log(H+)
S=ph+2b
what is the chemical formula for thymol blue
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
Molecular formula is C2H6O2 Maybe pH is 7. I measure the PH of ethylene glycol myself with az 8686 PH meter. The number that i saw was 8. I thinck its because of hydroxyl group(OH) in its Molecular formula(HOCH2CH2OH=C2H6O2).
-log [h30+]
The pH depends on the temperature.
