Interpretation: Compare the intensity of colour in the two Nessler cylinders by viewing vertically downwards towards a white background. For passing the test, the depth of colour generated during the test sample shouldn't be much more than that with the common.
The precipitate of heavy metal sulphide shaped presents colour. Dilute acetic acid and ammonia are used to take care of pH among 3.0 and 4.0 so that the precipitate formed is colloidal and uniform. The saturated Remedy of hydrogen sulphide must be prepared freshly for the experiment. Here hydrogen sulphide gas check here is created utilizing a specifically devised equipment named as Kipp’s apparatus through which ferrous sulphide sticks are made to respond with equivalent volumes of concentrated hydrochloric acid and drinking water.
