The pH of a buffer solution that is made by mixing 124 mL of 0.156 M of acetic acids (pls=4.74) with 56.8 mL of 0.106 M sodium acetate is ?
Suppose that a 1000 mL buffer (pH=5) solution will be prepared using 2.6g C6H5COOH (its Ka is 6x10-5) and 2.6g NaC6H5COOH in H2O. How much (in g) of the component of the buffer should be added in the 1000mL buffer so that its pH will be 3?
A buffer solution is formed by adding 0.200 moles of solid potassium nitrite, KNO₂, to 500.0 ml of 0.500 M Nitrous acid, HNO₂ solution. You may assume that the change in volume is negligible upon addition of the solid. pKa of HNO2 is 3.40 Ka of HNO2 is 4.0E-4 m.w. of HNO2 is 47.01 g/mol pH of the buffer solution is 3.30, so now Calculate the pH of the buffer solution after the addition of 5.00 ml of 2.50 M Ba(OH)₂.
A buffer solution is made that is 0.409 M H2S and 0.409 M in NaHS. If Ka1 for H2S is 1.00x10^-7, what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.087 mol NaOH is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter.)
The graph below, which is related to a titration curve, shows the fraction (f) of the stoichiometric amount of acetic acid present as non-ionized CH3COOH and as acetate ion, CH3COO-, as a function of the pH of the solution containing these species. (Graph piture attached) Explain the significance of the point at which the two curves cross. What are the fractions and the pH at that point?
Calculate the ratio of [Ca2+ ] to [Fe2+ ] in a lake in whichthe water is in equilibrium with deposits of both CaCO3 and FeCO3. Assume that the water is slightly basic andthat the hydrolysis of the carbonate ion can, therefore, beignored.

A buffer solution is made such that the initial concentrations of lactic acid (HC3H5O3) and the lactate ion (C3HO-) are 0.600 M and 0.620 M, respectively. What is the resulting pH if 200.0 mL of 0.100 M potassium hydroxide is added to 0.600 L of the buffer solution? (The Ka of HC3H5O3 is 1.4 x 10-4.)
A titration curve is constructed by plotting the pH of the analyte solution versus the volume ofthe reagent added as the titration progresses. As the equivalence point is approached, there is arapid change in the pH. Titration curves enable us to explain how end points are detected andtheir relationship to equivalence points. They can also serve as guides for choosing the properindicators for a particular acid-base titration. Explain how each plot can be used to interpret the acid-base titration.
What is the pH of a 1.0 L solution that is 0.50 M PO43- and 0.50 M HPO42-?

If 0.01 moles of OH- is added to 1.0 L of water, what will the new pH be? Change of volume is negligible.
