∙ 12y agopH 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]

∙ 14y agoI 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.

∙ 9y agoThe formula for pH is pH = - log [H+]. pH refers to hydrogen ion concentration and is only applied to aqueous solutions.
Wiki User
∙ 10y agoBy definition pH = -log10([H3O+])
In water and water-solutions at 25oC: pH = 14 - pOH

∙ 12y agothe equation for finding pH is pH=log- (negative)
Wiki User
∙ 13y agopH = -log[H+]
(pH equals the negative log of the molar concentration of H+)
Wiki User
∙ 6y agopH=-log[H+]
Edited: it is also pH = 14 - pOH. That is certainly an equation for pH.
Wiki User
∙ 6y agopH = -log [H3O+]pH = 14 - pOH
pH + pOH = 14

What is the hydrogen ion concentration from pH 3.82?
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.
A solution with a pH value smaller than 7 would be a?
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+])
What is the chemical equation of alkali soil?
If you think to "soil" this hasn't a chemical formula or equation. This soil has a pH over 7.
What is the pH for 1M Na2C4H2O4?
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.
What is the pH of H plus?
The H in pH stands for hydrogen.If the pH is 5, then the concentration of hydrogen ions is 10-5 moles per liter.
What is the equation for determining pH?

Why is the phosphate buffer made up by using the Henderson hasselbalch equation not the expected PH?
1. Why is the phosphate buffer made up by using the Henderson-Hasselbalch equation not the expected pH?
What is Henderson-Hasselbalch equation?
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
What equation is used to calculate the pH of a solution?
pH = -log [H+(aq)]. In words, pH is the negative logarithm (to the base 10) of the hydrogen ion concentration.
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
A solution with a pH value smaller than 7 would be a?

What is redox pH?
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
