In 100 mL of distilled water, 2 g of TlCl is added. What will be the excess mass of solid? In other words, how much of the 2 g of TlCl doesn't dissolve? The Ksp of TlCl is 3.6 x 10-6.

Is there a compound TiCl? I know of TiCl2, TiCl3 and TiCl4 but not TiCl. I don't want to waste my time on a compound that doesn't exist. Thanks.
