It is safe to touch or taste a chemical to find out whether it is an acid.
When sulfuric acid and sodium hydroxide react together in the right amounts, what do they make?
In the Brønsted–Lowry definition, what is an acid?
Hydrochloric acid is called a strong acid. What does 'strong' mean here?
What volume of 0.2 M NaOH, in millilitres, exactly neutralises 100 mL of 0.1 M HCl? (HCl and NaOH react 1:1.)
In a 0.100 M solution of acetic acid, about 1.3% of the acid molecules are ionised. What does this tell you?
In NH₃ + H₂O ⇌ NH₄⁺ + OH⁻, identify the two conjugate acid–base pairs and explain water's role.
HCl, HBr and HI all behave as equally strong acids in water. Why, and how can chemists tell which of them is strongest?
