pKa of Salt of Weak acid and Strong base Solution

Follow our step by step solution on how to calculate pKa of Salt of Weak acid and Strong base?

FIRST Step Consider the formula

pk a = 2 \cdot pH - 14 - \log 10 (C salt)

Next Step Substitute values of Variables

∴

pk a = 2 \cdot 6 - 14 - \log 10 (1.8E-6mol/L)

Next Step Convert Units

∴

pk a = 2 \cdot 6 - 14 - \log 10 (0.0018mol/m³)

Next Step Prepare to Evaluate

∴

pk a = 2 \cdot 6 - 14 - \log 10 (0.0018)

Next Step Evaluate

∴

pk a = 0.75448733218585

LAST Step Rounding Answer

∴

pk a = 0.7545
