Take advantage of this causticizing efficiency calculator tool that helps you to calculate the causticizing efficiency by providing the number of reactors. To use this calculator tool, all you need to do is give the inputs in the given boxes and click on the calculate button that gives you the answers instantaneously.

Quantity of Sodium Hydroxide(NaOH):
Quantity of Sodium Carbonate(Na2CO3):

What is Causticizing Efficiency?

Causticizing efficiency refers to the chemical process, where the green liquid is converted into white liquid. While the causticizing reaction is going on, the green liquid in the sodium carbonate reacts with the calcium hydroxide to form sodium hydroxide. Based on this causticizing degree, we can define the totality of reaction at equilibrium.

The formula of this causticizing efficiency is,


NaOH = Sodium Hydroxide

Na2CO3=Sodium Carbonate

How to Calculate Causticizing Efficiency?

Below is the step-by-step process to calculate the causticizing efficiency. If you use these guidelines to calculate you will get the right answers.

  • Firstly, write the values that were given in the problem.
  • Next, apply the formula.
  • Substitute the values and simplify them.
  • Finally, you will get causticizing efficiency.

Causticizing Efficiency Examples

Question: Calculate the causticizing efficiency if the sodium hydroxide is 13 and the sodium carbonate is 6?


Given values are,

Sodium hydroxide = 13

sodium carbonate = 6

Apply the formula,

Causticizing Efficiency = [Quantity of NaOH / Quantity of (Na2CO3 + NaOH)] * 100.

= [13/ (13+6)] * 100

= 68.42 %

Therefore the causticizing efficiency is 68.42%.
