Acids and bases Acids - correct answer An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals PH - correct answer pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the...

AQA GCSE Chemistry - Required Practicals Correct Answers 2023. Making soluble salts using an insoluble base -method - ANSWER 1. Gently heat the dilute acid over a Bunsen burner. 2. Add the solid metal, metal oxide, metal hydroxide or metal carbonate to the warm acid until no more reacts. 3. Filter off the excess solid to produce a solution of the salt. 4. Gently heat the solution to evaporate some of the water to produce a saturated solution. 5. Leave the saturated solution to crystall...

Test for carbonates - - add dilute HCL - it makes carbon dioxide test for carbon dioxide by bubbling it through lime water Test for ammonium ions - -add sodium hydroxide -warm the mixture -hover damp red litmus paper over it , if it turns blue the ions are present Test for sulphate ionz (SO4 2-) - - add dilute HCL - then add BaCl2 - BaSO4 is made which is insoluble in water so a white precipitate will be formed Test for Halides (Cl-, Br-, I-) - - add nitric acid - add silver nitrate -...
