Salt preparation methods

Question 1

Titration

Answer 1

use an acid-base titration to find exact volume of soluble base that reacts with the acid. mix the correct proportions as this will produce a solution of salt and water. warm solution to evaporate water allowing salt crystals to form

Question 2

Precipitation

Answer 2

mix the 2 solutions together and filter to remove insoluble salt then wash with distilled water and dry salt with filter paper

Question 3

using carbonates and oxides

Answer 3

measure concentration of acid and add extra base for complete neutralisation and then filter off the solid and collect filtrate that contains salt. heat to evaporate water and remain with soluble salts

Question 4

titration is used for…
precipitation is used for…
oxide/carbonate method is used to…

Answer 4

soluble bases
making insoluble salts
make salts from insoluble bases
