Frequently asked questions
What is Inorganic chemistry?
Inorganic chemistry covers Periodicity, Group 2, the alkaline earth metals, and Group 7(17), the halogens in AS Level AQA Chemistry. 12 lessons in 3 subtopics.
How do you test for sulphate ions?
To test for sulphate ions, add excess dilute hydrochloric acid to the solution, then a few drops of barium chloride solution. The Group 2 Sulfates: Solubility, Testing, and Applications notes cover this in full.
How do you test for ammonium ions?
To test for ammonium ions, add sodium hydroxide solution and warm. The Chlorine and NaOH notes cover this in full.
How do you test for carbonate ions?
To test for carbonate ions, add dilute hydrochloric acid: effervescence shows CO₂ is produced, and the gas turns limewater milky. The Chlorine Reactions with Water notes cover this in full.
What is limewater?
Limewater is the name for calcium hydroxide, Ca(OH)₂, when it is dissolved in water. The Group 2 Hydroxides: Solubility and Uses notes cover this in full.
What are halogen displacement reactions?
In a halogen displacement reaction, a more reactive halogen oxidises the halide ion of a less reactive halogen. The Halogen Trends: Electronegativity, Boiling Point & Oxidising Ability notes cover this in full.
What is liming?
Liming is the agricultural process of adding Ca(OH)₂ or CaO to acidic soil to raise its pH towards neutral, around pH 6.5–7, which is optimal for most crops. The Group 2 Hydroxides: Solubility and Uses notes cover this in full.
What is the reaction of chlorine with water?
Chlorine reacts with water in a reversible disproportionation reaction, Cl₂ + H₂O ⇌ HCl + HClO, forming a pale yellow-green solution called chlorine water. The Chlorine Reactions with Water notes cover this in full.
What is the test for halide ions?
The test for halide ions has two stages: acidify with dilute nitric acid and add silver nitrate to get a white, cream or yellow precipitate, then add dilute and then concentrated ammonia. The Identifying Halide Ions: Silver Nitrate & Ammonia Tests notes cover this in full.
