Dip nichrome wire loop in concentrated hydrochloric acid, then in unknown compound, hold loop in clear blue part of flame 1 of 11 What do you observe for each Group 2 Metal? Ca 2+ - Brick Red, Sr 2+ - Red, Ba 2+ - Pale Green 2 of 11 How do you test whether a substance contains Ammonium ions? Add dilute sodium hydroxide, gently heat, if ammonium ions are present ammonia gas will be produced turning the damp red litmus paper blue 3 of 11 What is the ionic equation for when Hydrochloric Acid and Ammonium Ions react? . 4 of 11 How do you test for Hydroxide ions? Dip a piece of red litmus paper in the solution, if hydroxides are present the paper will turn blue 5 of 11 How do you test for Carbonates? Add dilute hydrochloric acid if it contains Carbonate ions it will fizz, bubble the gas through limewater if it goes cloudy a Carbonate is present 6 of 11 What is the ionic equation for when Hydrochloric Acid is added to a solution containing Carbonates? . 7 of 11 What is the equation for the reaction of Chlorine with cold dilute aqueous Sodium Hydroxide? . 8 of 11 What happens when you do further testing for Halide Ions by adding dilute Ammonia to the Silver Halides? . 9 of 11 Which Group 2 Hydroxide is most soluable, and what is the trend? Solubility increases down the group for hydroxides making Barium Hydroxide most soluable 10 of 11 What is the trend for the soluability of Group 2 Sulfates, and which is most soluable? Soluability decreases down the group for sulfates making Magnesium Sulfate most soluable 11 of 11
