Dip one Q-tip into concentrated hydrochloric acid (HCl) and a second cotton swab into concentrated aqueous ammonia (NH3). # = > ? Tiffanys Link Bracelet, nitric oxide). 3 - Place the small beaker into the larger one and cover with a watch glass. Controlled Variables The material that diffuses could be a solid, liquid or gas. Place one or two drops of the ammonia on the other swab. A white ring will form closer to the ammonia than the hydrochloric acid because ammonia has a lighter molecular weight than hydrochloric acid which means that the lighter particles can move faster 3. * t 0 6 4 4 Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass. The ammonia gas, having a lower molecular weight than the hydrogen chloride, will diffuse faster and travel a greater length of the tube. Sulfide, sulfur dioxide, carbon dioxide and ammonia fumes will come hydrochloric! #v T#vD Suppose ammonia and hydrochloric acid are introduced simultaneously at the opposite ends of 50.0 cm long glass tubing, calculate where in the tube the two gases will meet. In this experiment, the relative rates of diffusion of 2 gases, having significantly different masses, will be determined. Place the vials into 100 cm 3 beakers to catch drips and reduce the risk of tipping. Place cotton ball in dish with tweezers The molecular mass of HCl = 36.5. After about a minute the gases diffuse far enough to meet and a ring of solid ammonium chloride is formed. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas. Avoid breathing the vapors. The light from laser pointers May cause eye damage if shown directly into the eye, I ' going. Cotton wool soaked in concentrated ammonia solution, NH 3(aq) and concentrated hydrogen chloride solution. 1 Not only does it involve active student participation, but it also provides quantitative proof of Graham's law that relates the ratio of the rates of diffusion of two gases.
