Question

Why are metallic oxides basic & non metallic acidic?

Answer 1

@chmvijay

Answer 2

Also,
how do u learn chemical eqns? :S

Answer 3

bcoz metal always tend to give electrons to the oxygen so electron density on O increases so this is Lewis basic :) and non metallic are more electronegative hence attracts the electron density from the Oxygen atom making is less electron density hence they are acidic :)

Answer 4

how do u learn chemical eqns? what exactly ?

Answer 5

like
\[\Huge I_2+HNO_3->\]

Answer 6

does it form HI ?

Answer 7

umm no

Answer 8

what will I2 oxidize to?

Answer 9

that all u have to remember and have to put logic :) some time so reaction types u should know HNO3 is good oxidising agent right then it may be oxidation :) if it react with base then it will be salt formation reaction like that u have to judge

Answer 10

so what will I2 oxidize to

Answer 11

i mean only what will I2 oxidize to
I?

Answer 12

10 HNO3 + I2-->2 HIO3 + 10 NO2 + 4 H2O

Answer 13

nope NO3 get converted to NO2 in most of HNO3 used as reactant and water too

Answer 14

but I2 is getting oxidized too

Answer 15

check oxidation state ?

Answer 16

i just gave u example

Answer 17

hmm

Answer 18

only non metals get oxidized ? what about metals?
