実験手順

the potassium cryolite is sucked out and then fed into a rotary reaction kettle together with concentrated sulfuric acid, hydrogen fluoride gas as well as potassium sulfate and potassium aluminum sulfate are generated by reaction in the rotary reaction kettle, and the hydrogen fluoride gas is collected and then dissolved in water to obtain hydrofluoric acid; the solid mixture of potassium sulfate and potassium aluminum sulfate is crushed and then dissolved in water, potassium hydroxide is added for the purpose of reaction, and potassium sulfate aqueous solution is obtained after solid aluminum hydroxide is separated; the chemical reactions involved are as follows:
