Aluminium does not react with water at room temperature but reacts with both dil . Hcl and NaOH solutions . Verify these statements experimentally . Write your observation with chemiscal equation , From these observations , can we concluds that Al is a metalloid ?

Explanation

1) 'Al ' is a silverly white metal .The Surface of Al metal is convered with a thin layer of oxide that protect the metal from attack by air . If the mental oxide layer is damaged . The Al is exposed to attack , even by water .
2 ) Aluminum reacts with dil HCl , HCl dissolves Al and gives ` H_(2) ` gas .
`2Al +HCl to 2Al Cl_(3) + 3H _(2 ) uarr `
3 ) Aluminmum reacts with NaOH and liberates `H_(2) ` gas .
`2Al + 6H_(2) O + 2NaOH to 2Na[Al (OH)_(4) ]+ 3H _(2 ) `
4 ) the above two reactions says that Aluminium is amphoteric .
5 ) this shows that Al is a soft metal .
