1. Key Ideas

The same chemistry that makes your stomach acid dissolve food also makes antacids work — and the ability to name, identify, and predict acid reactions is the toolkit every calculation lesson in this module builds on.

Binary acid naming rule (hydro-/ic) and oxoacid naming rule (from ion name)
Why indicators change colour using the HIn ⇌ H⁺ + In⁻ equilibrium and Le Chatelier

2. Success Criteria

By the end, you should be able to:

Binary acid naming rule (hydro-/ic) and oxoacid naming rule (from ion name)
Names and formulas of the seven key acids and six key bases
Three common indicator ranges: methyl orange, bromothymol blue, phenolphthalein

3. Key Terms

Binary acidsA substance that donates protons (H⁺) or accepts electron pairs, according to context.

OxoacidsA substance that donates protons (H⁺) or accepts electron pairs, according to context.

-ateIf a system at equilibrium is disturbed, it will shift to minimise the disturbance.

-ic acidA substance that donates protons (H⁺) or accepts electron pairs, according to context.

Brønsted-Lowry acidA proton (H⁺) donor in an acid-base reaction.

Brønsted-Lowry baseA proton (H⁺) acceptor in an acid-base reaction.

2. Apply this idea to a new example: "Names and formulas of the seven key acids and six key bases". Show your reasoning clearly.

Band 43 marks

3. Analyse why this idea matters for understanding Nomenclature, Indicators & Predicting Acid Reactions: "Three common indicator ranges: methyl orange, bromothymol blue, phenolphthalein".

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Nomenclature, Indicators & Predicting Acid Reactions but does not use evidence or reasoning.

Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.

7. Multiple Choice

A. Identify the key concept being tested

B. Write every fact from memory

C. Ignore the command word

D. Skip examples and evidence

2. Which answer would show stronger understanding of Nomenclature, Indicators & Predicting Acid Reactions?

A. An answer with accurate terms and reasoning

B. A copied definition only

C. A single-word response

D. An answer with no example

3. What should you do if a question asks you to explain?

A. Link the idea to a reason or cause

B. List unrelated facts

C. Only draw a diagram

D. Write the shortest possible answer

8. Success Criteria Proof

Finish with evidence that you can do each success criterion.
