i know that sodium react with hydrochloric acid to form sodium chloride and(according to what i readed) free hydrogen. but i also readed in wikipedia that sodium hydride is made by the direct reaction of liquid sodium with hydrogen. so sodium hydride can be formed in good proportion by passing hydrochloride gas into liquid sodium?, and what about hydrochloride salts? sodium can also react with the hydrochloride to form sodium hydride and sodium chloride?. and another question, dose sodium hydride is pyrophoric? dose sodium hydride can be extracted from that reaction without inert atmosphere?
