Consider a buffer solution that is 0.50 M in NH3 and 0.20 M in NH4Cl. For ammonia, pKb=4.75. Calculate the pH of 1.0 L of the so
vladimir2022 [97]
You have 0.50 mol of NH3 and 0.20 mol of NH4+ to start (NH4Cl dissolves completely), given the molarity and 1.0 L solution.

30.0 mL of 1.0 M HCl is 0.0300 mol of HCl. This will react with the NH3 to produced 0.030 mol of NH4+.

You now have 0.47 mol NH3 and 0.23 mol NH4+. Now use the Henderson-Hasselbach equation to calculate your pH. The equation says to use concentration of acid and base, but you can just use the moles of them because it doesn’t make a difference.

pH = pKa + log(base/acid)

pKa = 14 - pKb = 14 - 4.75 = 9.25

pH = 9.25 + log(0.47/0.23) = 9.56

if an unknown sample solution is prepared by diluting 10.00 ml of the original solution to a total volume of 100.0 ml with deion
Usimov [2.4K]

The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.

Mathematically;

The dilution factor is given by the formula;

Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution

Final volume of the now diluted solution = 100.0 ml

Initial volume of more concentrated solution = 10.00 ml

Dilution factor = 100.0 ml/10.00 ml

Dilution factor =  10
