For the titration of 50.0 mL of a 0.100 M solution of a dibasic compound with 0.0500 M HCl, calculate the pH at 100mL (equivalence point) and at 145 mL. pka1=2.46 pka2=9.41 Homework Equations (1)pH=pka + log[BH+]/[BH2+] (2)[h+]=sqrt((K1K2F)+(K1Kw)/(K1+F)) The Attem...
Then, by using the molar ratio between KHP and NaOH (1:1), we can calculate the moles of NaOH used. Finally, by dividing the moles of NaOH by the volume of base used, we can calculate the concentration of the base. 3. To determine the moles of HCl needed to neutralize the given ...

involves calculating the Kb from the Ka, you are usually given the Ka and the Kw. For example, you may be asked to calculate the Kb of the chloride ion. The given Ka of the conjugate acid of the chloride ion, which is hydrogen chloride, is 1.0 x 10^6. The given Kw is 1.0 x ...
Given the dissociation constant Ka or its related quantity pKa of a weak acid dissolved in a solution of known pH, calculate the percent of the acid that dissolves.
How many milliliters of a 0.610 M NaOH solution are needed to completely neutralize 25.0 mL of a 0.356 M phosphoric acid solution? Oxalic acid is a diprotic acid. Calculate the percent of oxalic acid (H_2C_2O_4) in a solution giv...
