Potassium sulfate may react with copper, but generally, potassium persulfate or ammonia persulfate is used for copper etching, for example, 216224 or 248614.

General description
Potassium sulfate is an inorganic salt that can be prepared by reacting phosphogypsum and potassium chloride.[1] It forms needlelike mullite particles on heating with aluminum sulfate (Al2(SO4)3) and silicon dioxide (SiO2).[2] Its application to the soil has been reported to minimize the bronzing of rice plants.[3] Its surface integration growth kinetics has been obtained in the temperature range of 20-50°C.[4] The theoretical heat capacity curve of potassium sulfate in vapor phase has been obtained.[5]
Application
Potassium sulfate may be used as a sulfonating agent in the preparation of 4′-dibenzo-18-crown-6-sulfonic acid via sulfonation of dibenzo-18-crown-6.[6]
