Take some iron nails in test tube C and put some anhydrous calcium chloride in it and cork it. (v) Leave all the three test tubes for one day and then observe. Observation: Iron nails get rusted in test tube A because both air and water are present in it.
Fill half of the test tube Z with tap water and place a nail in it. Close the mouth of the test tube with a cork. Leave the three test tubes in this way for a few days and observe them. You will see that the nails in test tubes X and Y are rust-free, whereas the nail in test tube Z contains rust. please make me brain list
