Making Salts 0.0 / 5 ? ChemistryAcids, bases and saltsGCSEAQA Created by: Kate HCreated on: 08-05-14 19:59 Name 3 ways soluble salts can be made Metals, insoluble bases and alkalis 1 of 10 How can salts solutions be made into solid salts? Crystallisation 2 of 10 How can insoluble salts be made? Mixing solutions of ions to form a precipitate.Precipitate is filtered from the solution, washed and dried 3 of 10 What is an alkali? A soluble hydroxide 4 of 10 Why is ammonia useful? Dissolves in water to produce an alkaline solution. This is used to produce ammonium salts,which are used as fertilisers 5 of 10 What does metal and acid react to form? Soluble salt and hydrogen 6 of 10 How do you make a soluble salt from an acid and an insoluble base? Add to acid until no more will react and then filter off 7 of 10 How do you know when an alkali and acid have been neutralised? Add an indicator 8 of 10 Why is precipitation useful? Can be used to remove unwanted ions from solutions, treating effluent 9 of 10 What is the ionic equation for a neutralisation reaction? H+ + OH- >>> H20 10 of 10
