Name of the experiment : Chemical Test of water
Instruments : Glass Rod, Baeker, Burner , Triple stand with net wire
Chemicals : Anhydrous cobalt chloride , impure water sample
Experiment Details ; Anhydrous cobalt chloride was dissolved into sample water and heated with a bunsen burner. after evaporation of water the mixture was cooled.
Observation : Pink Color crystalline solid was found.
Inference : Supplied liquid sample was water.
Comment : Anhydrous cobalt chloride reacts with waterand produced pink colored cobalt chloride which is moistured.
Equation : CaCl2(s) + H2O →CoCl2.6H2O(S)
Anhydrous blue cobalt chloride was reacted with sample water and produced pink coloured cobalt chloride. Supplied liquid sample was water.
