Valpolicella Ripasso is a form of Valpolicella Superiore made with partially dried grape skins that have been left over from fermentation of Amarone or recioto. Winemaking in the region has existed since at least the time of the ancient Greeks.
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.
Barium chloride is the inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame.
