Determination of sulfuric acid content in the filter cake

If I want to determine the amount of sulfuric acid carried away in the filter cake, how can I do that?

If you’re afraid of the acidity, wash the residue with water. The wash water return system will do
What filter cake? Tell me about the components of your filter cake.
The filter cake contains inorganic salts (with a relatively high amount of ferrous sulfate), and it can be dissolved in water. Inorganic salts in the waste acid from the titanium dioxide industry
