Quickly convert the acid dissociation constant (Ka) to its pKa value with this easy-to-use calculator.
How to use the calculator
To use the pKa from Ka calculator, you need to enter the acid dissociation constant (Ka) value into the provided input field and press the “Calculate” button. The result will be dynamically displayed in the results section.
How it calculates the results
The calculator works by taking the input Ka value and using the following formula to calculate the pKa value:
pKa = -log10(Ka)
Where log10 represents the logarithm base 10 operation.
Limitations
This calculator only accepts positive numerical values for Ka. If you enter a non-numerical value or a value less than or equal to zero, you will receive an error alert. Additionally, the calculator does not account for significant digits or scientific notation. Please ensure your input is in a standard decimal format for accuracy.
