#23 - Acids, Bases and Salts

Edexcel IGCSE Chemistry - The Companion Audio Guide

Understand acids, bases, and salts: acids are proton donors, and bases are proton acceptors. Acids react with metals, bases, and carbonates to form salts, often releasing gases like hydrogen or carbon dioxide. Solubility rules predict if salts are soluble or form precipitates, aiding in practical salt preparation methods.
