What is the advantage of using a flame photometer instrument designed to operate with an internal standard ?
Mostly compounds of d block elements exibitcolour dueto d-d transistions between partially filled eg and t2gbut the reason for colour of KmnO4 and K2Cr2O7 is due to partial chanrge transfer between central atom and oxygen which causes colour
