How do you calculate pka?
how do you calculate pKa
How do you calculation pH from ka?
Ka = [H+][A-] / [HA] Hence [H+] = Ka[HA] / [A-] Remember pH = -log(10)[H+] 'logging' both sides. -log(10)[H+] = - log(10)Ka[HA] / [A-] By algebraic manipulation of log. pH = -log[A-]^-1 - logKa - log[HA] pH = log[A-] - logKa - log[HA] pH = pKa - log[HA]/[A-]
The pH of ethanol?
the pH of ethanol can be calculated using its pKa value (pKa 15.9) and the Henderson-Hasselbalch equation. pH = pKa - log [AH/A] where [AH/A] the ratio of disassociated versus undisassociated species in solution.
How do you find the pka value of a drug?
pKa of drug can be determined from Handerson Hasselbatch equation., when conc. of salt become equal to acid i.e. at equivalence point when pH=pka then in H-H equn, pH=pka
What pH of pka is 5.4?
This question does not make very much sense but it will somewhat be answered. PH is the measurement of a concentration of hydronium ions in a solution. PKA is the measurement of how much is available. If the concentration and pka of a substance is known, the pH can be calculated.

What is the formula for getting pH?
pH = pKa + log([A-]/[HA])

What is the pH of acetamide?
pKa approximently 17
How you can select buffer in hplc according to pka value?
By following + or - 2 pH to the pKa value
How do you get pKa with the pH of a solution?
pKa= pH - log(A/HA) to clarify -log is subtract log E.g A buffer is prepared by adding .15 M of NaOH and .1 of a weak acid, HA. If the pH of the buffer is 8.15, what is the pKa of the acid? pH= 8.15 - log .15/.1 = 7.97
What is the relation between pH and pOH?
pH = pKa + log([A-]/[HA]) pH = pKa+log([conjugate base]/[undissociated acid]) The actual meaning of pKa: the negative log of the dissociation constant, which is a measure of strength of an acid/base when pKa = pH, there is equal concentration of acid and its conjugate base. pKa helps to understand the nature of acid and base like pH: pKa 2 but 7 but < 10 -- weak base pKa >10 --strong base
What is definition of pka value and difference between pH and pKa?
A pKa value is a measurement used for bases and acids. The measurement pH applies to hydronium ion concentrations that are in a solution, whereas pKa only applies to determining the amount of dissociation an acid wants to do in a solution.
