H2 Chemistry Volumetric Practical Deep Dive: Acid–Base & Redox Mastery

Q: What does H2 Chemistry Volumetric Practical Deep Dive: Acid–Base & Redox Mastery cover?
A: A full Paper 4 volumetric playbook-apparatus standards, indicator selection, MMO routines, spreadsheet processing, and ACE commentary-mapped to SEAB’s 2026 H2 Chemistry practical requirements.

TL;DR
Paper 4 (SEAB 9729 Practical Assessment) runs 2 h 30 min, carries 55 marks, and is weighted at 20% of the H2 grade (Planning 5%, MMO/PDO/ACE 15% combined). Volumetric sequences recur almost every year and demand Class A glassware discipline, pre-planned indicator choices, and uncertainty-aware calculations.
Practise conditioning glassware, locking in concordant titres $≤0.10 cm³ spread$, automating stoichiometric math with spreadsheets, and writing ACE paragraphs that diagnose reagent and technique limitations.

Status: SEAB H2 Chemistry (9729, first exam 2026) syllabus and Chemistry Data Booklet last checked 2025-11-29 (syllabus PDF last modified 2024-07-17; booklet last modified 2024-12-17). Paper 4 remains 2 h 30 min, 55 marks, weighting 20 % with Planning at 5 % and MMO/PDO/ACE at 15 % combined; volumetric analysis stays in the Practical Assessment scope.

1 | Why volumetric analysis keeps returning in Paper 4

• The SEAB H2 Chemistry syllabus (9729, exams from 2026) flags volumetric work as a recurring Practical Assessment context spanning Planning (P), Manipulation & Measurement (MMO), Presentation of Data (PDO), and Analysis, Conclusions & Evaluation (ACE).
• Paper 4 runs 2 h 30 min, carries 55 marks, and is weighted at twenty percent of the final grade. Volumetric components often form one half of the investigation pair, alongside qualitative analysis or kinetics.
