Swix has heard about the ion exchange resin, but Swix has no idea what it is. What is it? Can you buy it cheaply?
Swix has just added 10mL of H2SO4 to 100mL of 20% solution of K2HPO3 and KH2PO3. A white precipitate was noted that appeared to be of crystaline nature resembling frosty stars. The precipitate was seemingly redisolving. 50mL of MeOH was added. This crashed out a thick white mess. There were bubble evolving.
What happened? What's the gas? The idea was to convert the phosphite into phosphorous acid. Then add MeOH so H3PO3 can go into it. And add enough MgSO4 to push the acid into MeOH since MgSO4 is more soluable in water than H3PO3.
Any ideas? My first idea is that its K2SO4 crashing out of the super saturated solution because due to my calculations there should be about 10g of K2SO4 formed more than 100mL of water can hold. The gas could have been simply air bubbles.
