I know a lot of reactions that use sodium hydroxide are hard to do in regular glassware because of how sodium hydroxide will corrode glass. However, experimentation seems to reveal that potassium hydroxide is far less corrosive to glass than its sodium counterpart. WebJan 1, 2024 · Initially, the HF solution etches the glass and insoluble by product deposited on top of the glass surface. As time progresses, the size of insoluble by-products becomes larger and accumulates to interfere with etching of glass. However, HCl (other oxide series) releases impurities in HF-HCl mixed solutions [16].
