Dissociation constant of Weak Acid Ka given Concentration of Weak Acid and its Ions Solution

Follow our step by step solution on how to calculate Dissociation constant of Weak Acid Ka given Concentration of Weak Acid and its Ions?

FIRST Step Consider the formula

K a = \frac{H + \cdot A -}{HA}

Next Step Substitute values of Variables

∴

K a = \frac{25mol/L \cdot 20mol/L}{17mol/L}

Next Step Convert Units

∴

K a = \frac{25000mol/m³ \cdot 20000mol/m³}{17000mol/m³}

Next Step Prepare to Evaluate

∴

K a = \frac{25000 \cdot 20000}{17000}

Next Step Evaluate

∴

K a = 29411.7647058824

LAST Step Rounding Answer

∴

K a = 29411.7647
