WebGiven acids or bases at the same concentration, demonstrate understanding of acid and base strength by: 1. ... 2.1 Atoms and reactions. 2.1.4 Acids. b) qualitative explanation of strong and weak acids in terms … WebThis video is covers what acids and bases are, what the pH scale is, how we measure pH with indicators and probes, and what neutralisation reactions are. convex set mathematical definition WebCarboxylic acids have a functional group made up of a C=O bond and C-OH bond on the same carbon, which is simplified to COOH. Carboxylic acids can be named. As we have seen with alkanes, alkenes and alcohols, carboxylic acids can also be named. The first four alcohols in the homologous series are called methanoic acid, ethanoic acid, propanoic ... Web-substances that react with acids to form salt and water (sometimes co2)-metal oxides, metal carbonates-bases are chemicals which can neutralise acids and produce salt and … convex set proof WebTo investigate the effect of changing the concentration on the rate of a reaction. Calcium carbonate reacts with dilute hydrochloric acid: calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide. CaCO 3 (s) + 2HCl(aq) → CaCl 2 (aq) + H 2 O(l) + CO 2 (g) The volume of carbon dioxide gas produced can be measured ... WebGCSE/IGCSE KS4 Science-Chemistry examination ('exam') practice questions for the symbol equations for the for the reactions of acids with metals, oxides, hydroxides and carbonates and hydrogencarbonates.

Na 2 S 2 O 3 (s) + 2HCl(aq) → 2NaCl(aq) + H 2 O(l) + SO 2 (g) + S(s) The sulfur forms a cloudy yellow-white precipitate during the reaction. The time taken for this to achieve a given cloudiness provides a way to measure the reaction time. Method
