properties and stability
stability and reactivity:
materials to avoid: moisture, moisture.
products to be decomposed: carbon monoxide and carbon dioxide.
86g of rubidium acetate can be dissolved in 100ml of water at 45℃, and 89g of rubidium acetate can be dissolved in 100ml of water at 99℃. it is hygroscopic and should be kept airtight.
storage method
storage:
seal the container and store it in a sealed main container in a cool, dry place.
synthesis method
add an appropriate amount of rubidium carbonate to the excess acetic acid aqueous solution in batches until carbon dioxide no longer escapes. heat for a moment, filter, add a small amount of acetic acid to the filtrate, concentrate the filtrate, let it stand, crystals will precipitate, and filter with suction.
