How do you calculate the change in pH in a chemical reaction?
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.
How is the process of calculating pH changes in buffers carried out?
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.
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.
May i know 'the word equation for neutralization reaction' and what is the the pH value of it?
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
What is the pH of a .12 M solution of monochloroacetic acid?
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.
What is the equation for determining pH?
pH = -log[H+]
What is the pOH equation How can pOH be determined from pH?
pH + pOH =14
What has the author Ph W Zettler-Seidel written?
Ph. W. Zettler-Seidel has written: 'Nomograms for three ramjet performance equations (continuity equation, pressure equation, combustion equation)'
How do you derive the isoelectric point equation from Henderson hasselbalch equation?
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.
Calculate the pH after mixing a buffer at pH 4 and 6?
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.
Write the equation for determining pH?
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
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+]
What is Ph of lactic acid having pka of 4.4 when its 20 percent dissociated?
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.
