Why does phenolphtalein change colour during the production of gas?the phenolphtalein changes colour after a piece of calcium carbide was dropped into the water. Note: phenolphatalein is an acid/base indicator.
While 1.22 g of a white solid, supposed of being pure cocaine, a molecular compound, is dissolved in 15.60 g of C6H6 the freezing point is lowered by 1.32 ¬0C. Compute the molar mass of the solid. Kf value for benzene = 5.12C/m.
