Sorry! Didnt bold on purpose, I must have accidentally done it!
All 3 will be using the same ionic equation right? And I have to talk about the chromate/dichromate equilibrium for everyone of them?
Ba++ + CrO4-- <----> BaCrO4 &
2CrO4-- + 2H+ <-----> Cr2O7-- + H2O
2) Oh, so Cl- does...
1. Recently did a lab experiment involving Barium Chromate.
1) When BaCl2 and K2CrO4 were mixed, I obtained a colourless solution and a yellow ppt was formed. This solution and ppt were split into 3 test tubes.
2) When HCl was added to tube 1, i got an observation that an orangey yellow...
