pH = -log[H+]
where H+ equals the concentration of hydrogen ions in a given solution.
To calculate the change in pH in a chemical reaction, you can use the Henderson-Hasselbalch equation. This equation relates the pH of a solution to the concentration of the acid and its conjugate base. By knowing the initial concentrations of the acid and base, as well as the equilibrium concentrations after the reaction, you can calculate the change in pH.
The process of calculating pH changes in buffers is carried out by using the Henderson-Hasselbalch equation, which relates the pH of a buffer solution to the concentration of its acidic and basic components. This equation allows for the prediction of how the pH of a buffer solution will change when the concentrations of its components are altered.
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.
The pH value of neutralisation is pH7 because pH1 is a strong acid, pH14 is a strong alkali. However I to am trying to find the word equation as I have a test tomorrow that I need to revise for. Good luck hope this has helped
The pH of a .12 M solution of monochloroacetic acid can be calculated using the equation pH = pKa + log([A-]/[HA]), where pKa for monochloroacetic acid is about 2.83. The concentration of A- (chloroacetate ion) can be found by multiplying the initial molarity by the degree of dissociation. Once these values are plugged into the equation, the pH can be determined to be around 2.78.
pH = -log[H+]
pH + pOH =14

The isoelectric point (pI) is the pH at which a molecule has no net charge. To find pI from the Henderson-Hasselbalch equation, set the net charge of the molecule equal to zero and solve for pH. This equation is derived by considering the acidic and basic dissociation constants of the molecule to calculate the pH at which the net charge is zero.
The pH after mixing two buffers can be calculated using the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid. Given pH of 4 and 6, the pKa can be determined and used in the equation to find the final pH value after mixing.
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
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+]
The pH of a solution containing lactic acid at 20% dissociation can be calculated using the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), where the pKa of lactic acid is 4.4. Given that lactic acid is 20% dissociated, [A-] = 0.2 and [HA] = 0.8. Plugging these values into the equation gives pH = 4.4 + log(0.2/0.8) ≈ 3.4.
