% Un-ionized Ammonia Calculator

To use the un-ionized ammonia calculator, simply enter your values for Temperature (in C) and pH in the boxes below and then click on the “Calculate Now” button. The program will display the percentage of total ammonia that is un-ionized.

If you include an ammonia concentration, the program will respond with both the Percent and the Concentration of un-ionized ammonia. Please Note: you do not have to enter a Concentration. Also be aware that the program rounds values to 3 decimals, a reasonable limit to the precision of ammonia measurements.

pH :
Ammonia Concentration *Optional: mg/L
Percent: %
Unionized: mg/L
