Production of chloride using nitrate and sodium chloride Aim of the activity The aim of the activity was to produce the insoluble salt silver chloride using the soluble salts silver nitrate and sodium chloride that I prepared in unit 1 activity 2aAB + CD = AD + CB================= silver nitrate + sodium chloride = silver chloride + nitrate Sodium Portfolio Tests – (Lukas Chamberlain) Activity 3.1-3c: Precipitation Safety Points Sodium Chloride · Wear safety glasses · Do not eat · Use the smallest amount possible on a watch glass to avoid contamination of the bottle · Test for sodium last as nichrome wire is difficult to clean afterwards · Wear suitable protective clothing · In case of splashes in the eyes: In case of contact with eyes, rinse immediately with cold water and consult a doctor · If spilled on the floor: collect and clean the surface · If spilled on skin or clothing: wash away · Irritant Silver nitrate · Wear safety glasses · Wear protective glasses · Use the minimum volume and the smallest volume necessary · Wear suitable clothing · If spilled in eyes: rinse eyes for ten minutes · If spilled on the floor: collect and wash the surface · If spilled on the skin: wash thoroughly · Corrosive · Irritant · Oxidant · Environmental hazard Silver chloride None listed Sodium nitrate None listed Portfolio evidence – (Lukas Chamberlain) Activity 3.1-3c: Precipitation Method and Material1. I carefully measured 10cm3 of silver nitrate using a 10cm3 graduated cylinder for accuracy. I did it over a sink, and then I spilled... half the paper... that also means that the safety points are probably bigger because there is a risk of more spilling and that would cause more damage. Silver nitrate is also produced to a higher level of precision as less is wasted which means more profit. Portfolio Evidence – (Lukas Chamberlain) Activity 3.1-3c: Precipitation Observations during the procedure I observed that the washings I collected after filtering the precipitate were cloudy demonstrating that it still contained particles of silver nitrate as it is an insoluble salt and does not dissolves in water. Portfolio Evidence – (Lukas Chamberlain) Activity 3.1-3c: Precipitation Summary This experiment prepared silver chloride by a precipitation reaction between silver nitrate and sodium chloride. The silver chloride was filtered and the yield was calculated.
