ABSTRACT:
A chemical solution preparation apparatus for preparing a chemical solution from chemical gas of an industrial chemical grade. A dissolution unit dissolves the chemical gas in pure water, which is contained in a tank. A gas discharge control unit controls the amount of chemical gas discharged from the dissolution unit. A liquid discharge discharges a predetermined amount of the chemical solution from the tank. At least one of the gas discharge control unit and the liquid discharge control unit are operated at substantially the same time as the dissolution unit.
