چکیده
A method IS presented for determmmg the dlstnbuhon of reaction products and the stolcluometnc coefficient for the reachon of mud acrd (HF/HCl) with various mmerals To Illustrate the techniques, the drssolutmn of two common ahmuno-slllcates. potassmm feldspar and kaohmte, m mud acid IS mveswated for various temperatures and acid concentrations After determmmg the product dlstibuhon from the ~omc equtibrmm relatlonsbps mvolvmg the various fluonde Ion complexes, the stoictiometnc coefficient [moles HF consumed per mole mmeral dissolved] IS amved at through a numerical solution of the coupled equdlbrmm and mole balance equations The HF acid stolchometnc coefficient was found to decrease srgnlficantly with mcreaslng temperature and HCl acid concentrat*on This mformatlon IS of great tmportance m determlmng design condltlons for the matruc acid stunulatlon of 011 reservous
