Answer to Question #314816 in General Chemistry for deniz

Question

when stored in containers made of sodium silicate, hydrofluoric acid attacks the container to give hexafluorosilicic acid, sodium fluoride and water. write and balance the reaction between sodium silicate and hydrofluoric acid. how many grams of hydrofluoric acid is needed to completely dissolve a 100.0-gram weighing beaker made of sodium silicate?

Answer 1

Hydrofluoric acid attacks all silica containing materials, including glass. It must be used and stored in polyethylene (PE) bottles and vessels. Bottles for storage of HF must have secure caps and lids that can provide a gas-tight seal to prevent escape of hydrogen fluoride gas.
