Dear Chari,

To reduce the acidity of Phospo Gypsum there are two ways:

First is you should procure aged phospo gypsum whose pH is increased significantly by aging or by natural methods

Secondly, addition of lime powdwer. The lime powder acts as a neutralizer by reacting with H2SO4, thus reducing pH. For this you have to first perform lab test that what percent of CaO powder to be added to acheive a desired pH.

Thanks

Manish
