This core practical involves determining the concentration of an aqueous solution of hydrochloric acid by titration against a standard sodium hydroxide solution. Students use a volumetric pipette to measure fixed volumes of acid or alkali, a burette to deliver the titrant, and an appropriate indicator (e.g. phenolphthalein or methyl orange) to identify the end point. The activity develops skills in accurate measurement, titration technique, and stoichiometric calculations.

This risk assessment supports Core Practical 2, where learners determine the concentration of an aqueous sodium hydroxide solution via titration with a standard acid. The document follows a CLEAPSS‑aligned format and includes GHS hazard symbols, technician notes, student safety guidance, and teacher‑led control measures suitable for high‑school chemistry laboratories.

A complete, classroom‑ready risk assessment for Pearson Edexcel IAL Chemistry Core Practical 1, supporting safe delivery of the experiment used to measure the molar volume of carbon dioxide gas. Ideal for teachers preparing practical lessons, technician setup, and CPAC‑aligned documentation. This resource outlines all key hazards, control measures, PPE requirements, and emergency actions linked to the reaction between calcium carbonate and ethanoic acid. It is fully aligned with Practical Techniques 1, 4, and 11 and mapped to CPAC statements 1a, 2a, 2b, 3a, 3b, and 4a.

Risk Assessment – Melting and Freezing of Stearic Acid (4CH1) This practical is low‑risk and suitable for GCSE/IGCSE Chemistry classes when standard laboratory precautions are followed. Students heat stearic acid gently in a boiling tube, record temperature changes, and observe the cooling curve as the substance solidifies.

A complete, CLEAPSS‑aligned risk assessment for Edexcel International GCSE Chemistry (4CH1) Core Practical 1: Effects of Temperature on Solubility. This resource clearly outlines all relevant hazards, GHS pictograms, control measures, PPE requirements, technician guidance, and safe‑working notes for solubility experiments involving salts such as potassium nitrate and sodium chloride. Designed in a high‑school‑appropriate format to support teachers and technicians in delivering this practical safely and consistently. Ideal for departments seeking reliable, ready‑to‑use safety documentation.

A clear, classroom‑ready risk assessment for Edexcel International GCSE Chemistry (4CH1) Core Practical 2: Chromatography. This document outlines all relevant hazards, GHS‑aligned pictograms, control measures, PPE requirements, and technician notes for paper chromatography using common solvents and food‑colour dyes. Structured in a high‑school‑appropriate CLEAPSS‑style format, it supports safe, consistent delivery of the practical and helps departments meet essential safety and compliance expectations.
