pKa of Acidic Buffer using Henderson's Equation Solution

Follow our step by step solution on how to calculate pKa of Acidic Buffer using Henderson's Equation?

FIRST Step Consider the formula

pK a = pH - \log 10 (\frac{C salt}{C acid})

Next Step Substitute values of Variables

∴

pK a = 3 - \log 10 (\frac{50mol/L}{15mol/L})

Next Step Convert Units

∴

pK a = 3 - \log 10 (\frac{50000mol/m³}{15000mol/m³})

Next Step Prepare to Evaluate

∴

pK a = 3 - \log 10 (\frac{50000}{15000})

Next Step Evaluate

∴

pK a = 2.47712125471966

LAST Step Rounding Answer

∴

pK a = 2.4771
