You can test for sulphates with Hydrochloric Acid and Silver Nitrate
You add Sodium Hydroxide (NaOH) to an unknown solution and a reddish-brown precipitate is formed. What metal ion was in the solution?
Copper
Iron (II)
Iron (III)
Calcium
To test for Oxygen, you put a glowing splint into a test tube of Oxygen and it relights the splint
Ammonia turns damp blue litmus paper blue
You have an unknown sample. When you do the flame test, you get a lilac flame and when you add Nitric Acid and Silver Nitrate to it, a cream precipitate is formed. What is the name of the sample?
Potassium Bromide
Sodium Iodide
Calcium Iodide
Calcium Chloride
You have an unknown sample. When you add Sodium Hydroxide and Ammonia, a blue precipitate is formed and when you add Hydrochloric Acid and Barium Chloride to it, a white precipitate is formed. What is the name of the sample?
Iron (II) Chloride
Copper Sulphate
Lithium Bromide
Iron (III) Iodide
Before doing a flame test, you must dip the loop of platinum wire that you will use in Nitric Acid
To test for Hydrogen, you...
Put a glowing splint in the test tube and hydrogen relights it
Put a lit splint in the test tube and the flame goes out
Put a lit splint in the test tube and a 'squeaky pop' sound is heard
It turns red litmus paper blue
Hydrochloric Acid can cause some samples to release a gas, which turns limewater cloudy. What is the anion in the sample?
Chloride
Sulphate
Carbonate
Hydroxide
Cations are negative ions
If you add water to Anhydrous Copper (II) Sulphate, what colour do the crystals turn?
Blue
White
