Solubility of orcinol in water
WebAccording to Henry’s law, for an ideal solution the solubility, Cg, of a gas (1.38 × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution (101.3 kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k .

If a small piece of sodium is dropped into some ethanol, it reacts steadily to give off bubbles of hydrogen gas and leaves a colourless solution of sodium ethoxide, CH 3 CH 2 ONa. Sodium ethoxide is known as an alkoxide. If the solution is evaporated carefully to dryness, the sodium ethoxide is left as a white solid. birthday freebies sydney
