Equal volumes of 0.10MNa2SO4(aq) and 0.10MBa(NO3)2(aq) are mixed at room temperature. Which of the following best describes the macroscopic observation immediately after mixing?
(a) No visible change occurs because all species remain soluble.
(b) A white solid forms because BaSO4 is insoluble.
(c) Gas bubbles appear as sulfate ions decompose to SO2(g).
(d) A white solid forms because Na2SO4 is insoluble in water.
