looking at it,… will ID Copper sulphate CuSO4 , it will be blue
adding AgNO3,… will ID NaCl , it will give a white ppt
adding BaSO4… will ID Na2SO4,… it will give a white ppt….(assuming that the solution was not blue)
if it was not blue, & no reaction happened with AgNO3 or BaCl2, it ID’s NaNO3 by default
