VCE Chemistry at Year 12: what the curriculum expects

VCE Chemistry Units 3 and 4 covers fuels and energy, equilibrium, electrochemistry, organic chemistry and analytical techniques.

This topic sits inside the VCE study design for Year 12 science; the questions stay at the easy and at-level tiers so the result is a fair check of the foundations.

Common VCE Chemistry misconceptions tutors see

The distractors in this quiz are built from real misconceptions rather than random wrong numbers, so a specific wrong answer usually points to a specific gap. The ones we see most at Year 12:

• Equilibrium is thought to mean equal concentrations.
• Oxidation and reduction are swapped.
• Organic molecules are named from the wrong end.

None of these is a sign of low ability. Each is a reasonable idea that worked in an earlier year and needs replacing, which is exactly what a good explanation, or a tutor, does.

Practising VCE Chemistry with a Year 12 student

The habits that move VCE Chemistry from shaky to secure at Year 12:

1. Write equilibrium explanations in the standard form.
2. Learn the oxidation-reduction rules.
3. Name organic compounds from structures.

VCE science demands precise terminology and structured explanations. Make summary notes per area of study, practise past exam questions and mark against the study design.

How the 10 questions are chosen

The 10 questions are drawn from 21 eligible items on VCE Chemistry in our Year 12 science bank, all at the easy and at-level tiers. The selection is fixed for this address so a shared link shows the same quiz; press New set of questions or add ?seed= to the address for a different mix. Options are shuffled, no two questions share a stem, and the answer key is fetched from our server only after you submit, so it is not hidden in the page.

Because every question here is on VCE Chemistry, a low score is a clear signal and a high score is genuinely reassuring for this topic. What it cannot tell you is whether the other Year 12 science topics are equally secure, or how far above the year level the student can go; the free Skills Check covers both.

Question 1

VCE Chemistry

Avogadro's number is approximately…

9.8 1.6 × 10⁻¹⁹ 6.02 × 10²³ 3.14 × 10⁸

Question 2

VCE Chemistry

A student electrolyses molten aluminium oxide (Al₂O₃) using inert carbon electrodes, passing a constant current of 5.00 A for 2.00 hours. At the cathode, Al³⁺ ions are reduced to aluminium metal. Which calculation correctly gives the mass of aluminium deposited? (F = 96 500 C mol⁻¹, M(Al) = 27.0 g mol⁻¹)

Q = 5.00 × 120 = 600 C; mol e⁻ = 600 ÷ 96 500 = 6.22 × 10⁻³ mol; mol Al = 6.22 × 10⁻³ ÷ 3 = 2.07 × 10⁻³ mol; mass = 2.07 × 10⁻³ × 27.0 = 0.0559 g Q = 5.00 × 7200 = 36 000 C; mol e⁻ = 36 000 ÷ 96 500 = 0.3731 mol; mol Al = 0.3731 × 3 = 1.119 mol; mass = 1.119 × 27.0 = 30.2 g Q = 5.00 × 7200 = 36 000 C; mol e⁻ = 36 000 ÷ 96 500 = 0.3731 mol; mol Al = 0.3731 mol; mass = 0.3731 × 27.0 = 10.1 g Q = 5.00 × 7200 = 36 000 C; mol e⁻ = 36 000 ÷ 96 500 = 0.3731 mol; mol Al = 0.3731 ÷ 3 = 0.1244 mol; mass = 0.1244 × 27.0 = 3.36 g

Question 3

VCE Chemistry

A chemist titrates a 25.00 mL sample of a weak monoprotic acid HA (Ka = 1.8 × 10⁻⁵) with 0.100 mol L⁻¹ NaOH. At the equivalence point, which of the following correctly describes the solution, and why?

pH > 7, because NaOH is a strong base and always makes the solution alkaline regardless of the acid. pH < 7, because excess H⁺ ions from the weak acid remain in solution at the equivalence point. pH > 7, because the conjugate base A⁻ hydrolyses water to produce OH⁻ ions. pH = 7, because equal moles of acid and base have reacted and all HA is neutralised.

Question 4

VCE Chemistry

A student titrates 25.00 mL of 0.100 mol L⁻¹ NaOH with 0.150 mol L⁻¹ HCl. What volume of HCl is required to reach the equivalence point?

25.00 mL 16.67 mL 12.50 mL 37.50 mL

Question 5

VCE Chemistry

Ethanol (C₂H₅OH) can be produced by fermentation of glucose or by hydration of ethene. A chemist reacts 5.60 L of ethene gas (measured at STP, 0 °C and 100 kPa) with excess steam. The reaction has a 75.0% yield. What mass of ethanol is produced? (Molar volume at STP = 22.4 L mol⁻¹; M(ethanol) = 46.0 g mol⁻¹)

11.5 g 17.3 g 6.47 g 8.63 g

Question 6

VCE Chemistry

A buffer solution is prepared by mixing 0.200 mol of ethanoic acid (pKa = 4.76) with 0.100 mol of sodium ethanoate in 1.00 L of solution. What is the pH of this buffer?

3.76 4.46 5.06 4.76

Question 7

In a redox reaction, oxidation is…

Loss of protons Gain of electrons Loss of electrons Gain of neutrons

How to read a score out of 10

9 or 10 out of 10

The easy and at-level content is secure. The useful question now is how far above the year level the student can go, which a ten-item quiz cannot show. The free Skills Check adds stretch and challenge questions on every topic so you can see the ceiling as well as the floor.

7 or 8 out of 10

Solid, with one or two specific gaps. Look at which topic the incorrect answers came from (the results panel names the weakest topic) and spend a week on that topic before re-testing with a different seed.

5 or 6 out of 10

Some core ideas are shaky. The pattern matters more than the score: two misses in the same topic is a gap; misses scattered across topics usually means reading the question too fast. Either way, the Skills Check will tell you which.

4 or fewer out of 10

Foundations from an earlier year are probably missing, which is common and fixable. Try the quiz one year level down to confirm, then talk to a tutor about a short catch-up plan rather than more of the same practice.
