1.Metallic aluminium powder is soluble in which solvent as it is insoluble in water?

2.when metallic aluminium reacts with hydrochloric acid,nascent hydrogen generated react with arsenic impurities to form arsine but i cant balane this reaction.

Al + HCl + As2O3   =   AlCl3 + AsH3   + H2O


I tried this way but not getting water,instead getting oxygen.

4Al + 12HCl + 2As2O3  = 4AlCl3 +  4AsH3 + 3O2


hydrogen is not balancing properly,

where I am wrong or this reaction is not possible???

forgotten to mention that that solvent must be inert not chemically reactive atl east in above reaction so that i can use it in this above reaction

No, that's not written correctly.  Aluminum metal doesn't react with hydrochloric acid (a solution of hydrogen chloride gas in water) to generate AlCl3 and water, because AlCl3 is unstable in water, and reacts further.  Besides, you can't just pick random reactions to try to balance.  You have to have some knowledge of some of the products.  Generally experimentally, although there are some hints from solubility rules, electronegative, and more complicated methods.

And no, I doubt there is an inert liquid solvent for most metals.  Well, maybe mercury, or gallium.  Bu the result is more alloy than solution.
