barium chloride plus sodium sulphate yields barium sulphate plus sodium chloride
Barium sulphate to barium sulphate is NO CHANGE!
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy. This energy corresponds to a wavelength of light, which is emitted from the ion. This wavelength corresponds to green light, hence the green flame observed.
Barium phosphate (BaHPO4) is used for: - component of flame retardants - component of phosphors

The copper flame has a more energetic radiation.
A simple qualitative test is the flame test: barium has a pale/apple green color.
Yellow-Green
Bright Indigo
