For each reaction sulphate is reduced to give SO2, S, or H2S. H+ is not reduced and no hydrogen gas is formed ]]> 2020-07-21 04:12:43 UTC https://padlet.com/subhoshree15/9CQuestion5/wish/658947689 https://padlet.com/subhoshree15/9CQuestion5/wish/658947840 We can distinguish between the 2 liquids as when it reacts with zinc the dil.sulphuric acid will produce hydrogen (pop sound). Concentrated sulphuric acid will react with zinc .]]> 2020-07-21 04:12:57 UTC https://padlet.com/subhoshree15/9CQuestion5/wish/658947840 https://padlet.com/subhoshree15/9CQuestion5/wish/658948508 concentrated sulphuric acid is not used as a drying agent for hydrogen because it reacts with hydrogen.]]> 2020-07-21 04:13:53 UTC https://padlet.com/subhoshree15/9CQuestion5/wish/658948508 https://padlet.com/subhoshree15/9CQuestion5/wish/658951956 To remove water dehydrating agent is used and to remove moisture drying agent is used.
E.g. fused CaCl2,caustic potash,phosphorous pentaoxide are eg for drying agent]]> 2020-07-21 04:18:46 UTC https://padlet.com/subhoshree15/9CQuestion5/wish/658951956 https://padlet.com/subhoshree15/9CQuestion5/wish/658953277 Conc sulphuric acid is a strong oxidizing agent and if used it will produce SO2]]> 2020-07-21 04:20:31 UTC https://padlet.com/subhoshree15/9CQuestion5/wish/658953277
