Konsep dan Rumus Kimia CSCA
Setiap konsep dalam silabus beserta rumusnya — dan apa yang benar-benar pernah ditanyakan ujian asli.
Ujian CSCA dikerjakan dalam bahasa Mandarin atau Inggris — peserta memilih sendiri. Karena itu konsep dan rumus di sini disajikan dalam kedua bahasa tersebut; halaman ini menampilkan versi bahasa Inggris.

Struktur atom dan keperiodikan
Atomic Structure
How proton, neutron and electron counts relate, the rules governing electron arrangement and how it is written down, and the ideas of isotope and nuclide.
11 soal ujian asli · 4 kali ujianThe Periodic Table and Periodic Law
Periods and groups in the table, how properties trend across a period and down a group, and how to compare particle radii and non-metallic character.

Ikatan dan struktur
Chemical Bonding
How ionic and covalent bonds form and how to tell them apart, how bond type maps onto substance class, and what a Lewis structure says about bond formation.
5 soal ujian asli · 4 kali ujianChemical Formulae and Structural Representation
Writing formulae from valencies, and what condensed, structural and empirical formulae — and ball-and-stick versus space-filling models — each convey.

Jenis reaksi
Redox Reactions
Recognising redox by change in oxidation number and electron transfer, identifying oxidising and reducing agents, and how redox overlaps the four basic reaction types.
15 soal ujian asli · 4 kali ujianIonic Reactions and Ion Coexistence
The conditions under which an ionic reaction proceeds, what an ionic equation reveals about composition, and judging whether ions can coexist under stated conditions.

Larutan berair
Electrolytes and Ionisation
Telling electrolytes from non-electrolytes, strong from weak, the ionisation equilibrium of a weak electrolyte, and what makes a solution conduct.
8 soal ujian asli · 4 kali ujianAcidity, Basicity and pH
The ionic product of water and the definition of pH, pH calculations, why salt solutions can be acidic or basic, and comparing strong with weak acids.
9 soal ujian asli · 4 kali ujian
Laju dan kesetimbangan
Rate of Reaction
Expressing rate as a concentration change per unit time and calculating it, and how a catalyst and other conditions change that rate.
6 soal ujian asli · 4 kali ujianChemical Equilibrium
What equilibrium actually is and how to test for it, and which way the position shifts when temperature, pressure or concentration changes (Le Chatelier's principle).
