    hey

    i am doing some observations in class and was hoping if anyone could answer my questions

    I need to distinguish from Barium and calcium
    when tested with NaOH i got a very slight white percipitate
    when tested with H2SO4 i got a white percipitate
    when tested with pottasium chromate i got a bright yellow percipitate which turns into an orange soloution when tested with excess HCL
    when tested with carbonate i got a white percipitate

    can anyone identify which it is ; calcium r barium
