Sample HSC Year 12 Chemistry questions

These sample questions are visible on the page before login. They show HSC Year 12 Chemistry titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data with diagrams, tables, curves, and spectra before opening the demo.

HSC Year 12 Chemistry Acid-base reactions hard titration curve

1. A weak acid is titrated with a strong base. The curve shows the equivalence point above pH 7. Which statement is best supported?

Choices

The solution is basic at equivalence.
The equivalence point must be pH 1.
No salt forms.
The acid becomes a metal.

Explanation:

The conjugate base of the weak acid makes the equivalence solution basic.

HSC Year 12 Chemistry Equilibrium systems hard equilibrium diagram

2. In the chromate-dichromate equilibrium, adding acid shifts the system toward orange dichromate ions. Which side is favoured?

Choices

Dichromate ions
Chromate ions only
Water molecules only
No shift is possible

Explanation:

Adding H+ favours the side that consumes H+, producing more dichromate ions.

HSC Year 12 Chemistry Redox hard electrochemical cell

3. A galvanic-cell diagram labels the anode and cathode. At which electrode does oxidation occur?

Choices

The anode
The cathode
The salt bridge
The wire coating

Explanation:

Oxidation is loss of electrons and occurs at the anode in an electrochemical cell.

HSC Year 12 Chemistry Organic reactions hard organic pathway

4. A reaction pathway shows ethanoic acid reacting with ethanol under reflux. What ester is formed?

Choices

Ethyl ethanoate
Ethanol
Ethene
Sodium ethanoate only

Explanation:

A carboxylic acid plus an alcohol can form an ester and water. Ethanoic acid with ethanol forms ethyl ethanoate.

HSC Year 12 Chemistry Analysis hard mass spectrum

5. A mass spectrum has its tallest peak at m/z 43 and a molecular ion at m/z 88. Which peak is the base peak?

Choices

m/z 43
m/z 88
m/z 0
Every peak

Explanation:

The base peak is the tallest peak in the spectrum, regardless of whether it is the molecular ion.

HSC Year 12 Chemistry Catalysts hard reaction profile

6. A catalysed pathway on a reaction profile has a lower peak than the uncatalysed pathway. What has changed?

Choices

Activation energy decreases.
The products disappear.
Atoms stop being conserved.
The reaction becomes impossible.

Explanation:

A catalyst provides an alternative pathway with lower activation energy.

For parents comparing HSC Year 12 Chemistry support

HSC Year 12 Chemistry practice should help students connect chemical reasoning to visible evidence: titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data. These examples preview that visual reasoning before the no-login Chemistry demo.
