In this lecture we will discuss the reactions of acid with bases, metal oxides and metals seperately. Acid with metal When acids react with metals, the products are a salt and hydrogen. In general: Acid + metal → salt + hydrogen For example: Hydrochloric acid + magnesium → magnesium chloride + hydrogen 2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g) Zinc and iron also react with hydrochloric acid. Acids with bases (Neutralisation reaction) In acid-alkali neutralisation reactions, hydrogen ions from the acid react with hydroxide ions from the alkali: H+(aq) + OH-(aq) → H2O(l) Pure water is neutral (its pH is 7). A neutral solution can be produced if the correct amounts of acid and alkali react together. The change in pH during a neutralisation reaction can be measured using a pH probe and meter, or estimated using universal indicator solution and a pH colour chart. Acids with metal oxide A salt and water are produced when acids react with metal oxides. Metal oxides are bases, because they neutralise acids. In general: acid + metal oxide → salt + water For example: sulfuric acid + copper(II) oxide → copper(II) sulfate + water H2SO4(aq) + CuO(s) → CuSO4(aq) + H2O(l) For more Video Lectures for O Levels, A Levels, IB Diploma, AP Courses & Edexcel: https://www.megalecture.com    / megalecture   For Zoom/Whiteboard Subject Experts and Tutors and Free Online Trial Classes, Contact: [email protected]
