pH = -log[H+]
where H+ equals the concentration of hydrogen ions in a given solution.
pH is the concentration of hydrogen+ atoms in a solution. 7 or less is acidic. 7 or more is basic. lowest number is most acidic. highest is most basic. basic solutions are used in cleanin solutions like soap. acids are dangerous
The formula is PH=-Log[H30] so negative log times the concentration of acid
POH=-log[OH]
I think you're confused. pH is a measure of the acidity or basicity of a solution; it has no chemical formula because it's not a compound. Perhaps you're looking for the definition of pH in its equation form: -log[H+] or the negative logarithm of the hydronium ion concentration.
The formula for pH is pH = - log [H+]. pH refers to hydrogen ion concentration and is only applied to aqueous solutions.
By definition pH = -log10([H3O+])
In water and water-solutions at 25oC: pH = 14 - pOH
the equation for finding pH is pH=log- (negative)
pH = -log[H+]
(pH equals the negative log of the molar concentration of H+)
pH=-log[H+]
Edited: it is also pH = 14 - pOH. That is certainly an equation for pH.
pH = -log [H3O+]pH = 14 - pOH
pH + pOH = 14
pH = - log [H+] Rearranging the equation, you get [H+] = 10-pH so if you want to find [H+] when pH equals 3.82, just substitute in the equation. I don't have a calculator as of now, so you'll have to calculate yourself.
If you think to "soil" this hasn't a chemical formula or equation. This soil has a pH over 7.
An acid; pH is a measure of the [H+] of a system. A solution with high [H+] is acidic, and has a low pH, according to the equation: pH = -log10([H+])
The ph. for this 1M Na2C4H2O4 solution can be found using the kA and the equation pH = pKa + log([base]/[acid]) This salt Na2C4H2O4 is going to increase the concentration of base in the solution.
The H in pH stands for hydrogen.If the pH is 5, then the concentration of hydrogen ions is 10-5 moles per liter.
pH = -log[H+]
pH = -log [H+]
pH + pOH =14
Ph. W. Zettler-Seidel has written: 'Nomograms for three ramjet performance equations (continuity equation, pressure equation, combustion equation)'
pH = - log [H+] Rearranging the equation, you get [H+] = 10-pH so if you want to find [H+] when pH equals 3.82, just substitute in the equation. I don't have a calculator as of now, so you'll have to calculate yourself.
1. Why is the phosphate buffer made up by using the Henderson-Hasselbalch equation not the expected pH?
Its an equation you can use to find the pH of a solution. it is.... --- pH = pKa + log (Base/Acid) --- these may help too Ka = 10^-pKa Kw = Ka*Kb
pH = -log [H+(aq)]. In words, pH is the negative logarithm (to the base 10) of the hydrogen ion concentration.
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
An acid; pH is a measure of the [H+] of a system. A solution with high [H+] is acidic, and has a low pH, according to the equation: pH = -log10([H+])
If you think to "soil" this hasn't a chemical formula or equation. This soil has a pH over 7.
strong dependence of electrode potential on pH, pH-dependent redox potential, Ernst equation now includes the H+-acidity. Reduction potential thus decreases by 2.3RT/F = 0.059 V per pH unit, The pH dependence is given by -(0.059 m/n)pH(n=numbre of electrons, m=number of H+) in the equation Aox + mH+ + ne ↔ AredH2
